At the end of her Journey LP, when the game shows the names of the other players who were her companions, she expresses her hope that they see the video someday and know how grateful she was for their help.
In one of her Twitter posts, she shows off a photograph of her refrigerator. What's so special about that? It's covered in fanart that people have drawn for her. D'aaaw.
Almost every episode of Pokemon White starts with at least one new piece of fanart her fans have drawn.
Project Red Sun. A charity stream for the American Diabetes Association that Lucahjin did in honor of her late father, who had diabetes.
The whole concept of her "Relaxajin" channel. She's much more soft-spoken and gentle than she is on her main channel, and her Sir Swears-a-Lot tendencies disappear entirely. The whole channel was made with the express purpose of helping people deal with stress and/or get to sleep peacefully, and she's phenomenal at it. One YouTube commenter suggested she become a therapist.
At the end of Ocarina of Time Blind, when she does Ganon's Tower she has her Sages briefly reappear to revoice the relevant characters and thanks each of them in turn for their help.
