Blood Stain, by Linda Luksic Sejic (under the deviantART username Sigeel) is a Slice of Life webcomic that emphasizes a realistic, yet comedic take on the Mad Science genre. Elliot Torres is a chemistry major who has been searching for a stable job for two years. After being let go from a multitude of jobs for various reasons, she resorts to applying for a job rumored to be offered from a Mad Scientist. It turns out, despite first impressions, that there's nothing to fear from the so-rumored employer, Dr. Vlad Stein. Instead, humor ensues.Linda Luksic Sejic is also known for her work in Grimm Fairy Tales as well as being married to Stjepan Sejic, another professional comic artist with a webcomic.
Blood Stain provides examples of the following tropes:
Absent-Minded Professor: Dr. Stein embodies this trope; he manages to forget that he booked a flight for Elliot and later, when Elliot arrives at his house, he is perplexed at who is his visitor. He himself describes that his "time/space orientation is a little off".
Art Evolution: As a whole, the comic's pages have grown sharper, and Dr. Stein looks younger in later pages compared to his first appearances.
Einstein Hair: As expected from a not-quite-mad scientist, Dr. Stein sports a healthy crop of frizzled hair. Sigeel jokes that he has a special shampoo that gives his hair the appearance of bramble, and a sketch journal skin on her deviantART page shows Vlad using Static Electricity to make his hair stand up.
Empathic Environment: When Elliot has had success with holding onto a job, the atmosphere remains sunny. When she loses it and has to rush to the airplane to 'God-knows-where', it suddenly pours, and the rain later causes a blackout.
Facial Dialogue: Serge and Dr. Stein have one on page 48 regarding Elliot's presence.
Ghost Butler: When Elliot steps outside of a bathroom at Dr. Stein's residence, a draft slams the door shut. The house itself is anything but horrific, though Elliot perceives it as so.
Guttural Growler: Elliot has described Dr. Stein's voice on multiple occasions as intimidating; on page 28, she compares it to "sandpaper polishing a rusty can".
Hair Contrast Duo: Inverted from the standard blonde/brunette duo: Clara, the (albeit dyed) blonde, is responsible and takes multiple jobs to keep their family afloat, while Elliot, the brunette, would much prefer not having to worry that her family is in financial issues—though she understands the weight of their troubles.
Healing Shiv: As Sigeel draws in one of the Moonstone Gatecomics, Elliot's character's staff can heal Vlad's character's HP by bashing him over the head even if she has run out of mana.
High Turnover Rate: The assistant position Elliot strives for has been filled frequently before, and Serge shows support for Elliot for being so determined to take it despite how implausible it was that she arrived under the time limit Dr. Stein set up for her.
I Meant to Do That: When Elliot is explaining to a forgetful Dr. Stein that he had provided a plane ticket and hence she arrived at his house late at night, Dr. Stein hesitantly responds as if the question was a Secret Test of Character.
Infinite Canvas: Each 'page' is a long, horizontal stretch of panels, some almost fifty long.
I Need a Freaking Drink: Upon reflecting on Elliot's first day on the job, Dr. Stein ignores an explicit assessment and asks Serge for a coffee refill.
The Insomniac: Dr. Stein, who is otherwise prone to dropping asleep otherwise.
Not What It Looks Like: Elliot comes down from her first night of sleep at Dr. Stein's house to see the doctor wielding a knife with red blotches over his lab coat. It turns out to be from him spreading jam and ketchup over bread from brunch.
Off Model: On page 44, Elliot is shown with pepper spray in right hand, and then she offers a handshake with same hand. A few panels afterward shows that she still has that pepper spray in her right hand again. Originally, Sigeel drew the handshake with Elliot's left hand, but a watcher of the comic noticed this oddity, so Sigeel redrew those frames despite the inconsistency it created.
Painting the Medium: The color of text bubbles reflect the characters; Dr. Stein's text bubbles are always black with white text and outlines, and Serge's bubbles, when he yells, becomes yellow with red lines.
Rainbow Pimp Gear: In the MMORPG Moonstone Gate, Elliot asks what Dr. Stein's setup looks like under his cosmetic armor, and said setup is a mishmash of armor sets that optimize his character's stats but is, to put it lightly, aesthetically unappealing.
Punny Name: Vlad Stein's name is intended as a cliche science name as well as a slant rhyme of "Blood Stain".
Repeat After Me: Serge helps Elliot introduce herself to Dr. Stein after being frightened by their second impression, up to the point where he suggests for her to repeat "And I think Serge is smoking hot!"
Right Behind Me: In a dubiously canonical sketch comic, Elliot mimics Dr. Stein's position by dressing up and sitting in his chair, while the actual Dr. Stein appears behind her.
Running Gag: Coffee. Dr. Stein's work environment essentially requires caffeine, and as Serge's brew is... not the most appetizing, both Elliot and Dr. Stein frequently poke fun at the lack of respectable coffee and crave a good cup.
In one of Elliot's jobs, her employer explains the process of making candles to her, only to have it be received as a wall of "blah" and "mumble" from her perspective.
Clara is on the receiving end of one as Elliot hastily explains why she is running off—unable to absorb the the urgency of Elliot's situation and panicking later on.
What, Exactly, Is His Job?: Elliot and the readers are kept in the dark about the details about Dr. Stein's job beyond the fact that he works "for a science institute". Sigeel hints at it, though nothing has been revealed yet.
Sigeel has explicitly said that Dr. Stein's job will be revealed in a later strip.
Where The Hell Is Springfield?: The comic takes place somewhere in the Mediterranean, and Sigeel goes out of her way to obfuscate location names, substituting "somewhere in the asscrack" and "God-knows-where" in lieu of locations.
Why Do You Keep Changing Jobs?: The trope does not exactly fit, but Elliot simply can't hold onto a job that requires focus, which, essentially, means all of the ones she applies to.
You Have 48 Hours: Dr. Stein gives Elliot three hours to catch a plane, and, remarkably, she does so, though not without plenty of frustration from herself and her friends about this short notice.
You Didn't Ask: Elliot initially looks for an autoclave on her own in Dr. Stein's basement, figuring that doing so will show that she is a responsible person (in contrast to her bumbling behavior in previous jobs). However, after spending a few pages with no avail, she hesitantly asks Dr. Stein where the autoclave is; she is surprised to find that Dr. Stein just nonchalantly throws out its location instead of criticizing her absentmindedness.
