These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Eighth Doctor Adventures
Alas, Poor Scrappy: Sam was such a pointless character that you'd think you'd be happy to find out about her Bus Crash. But since Fitz is so broken up about it, you can't help but feel a little sad...
Big Lipped Alligator Moment: Halfway through Vampire Science the Doctor and a vampire break into a hairdresser's so she can give him a haircut (with wash and conditioner). This is never mentioned again.
Ensemble Darkhorse: Fitz may well be more popular than the Doctor himself in this line.
Foe Yay: The Doctor mostly just thinks it's hilarious that Sabbath literally "stole his heart", but there is quite a lot of legitimate sexual tension. Camera Obscura really lays it on thick between the Doctor and Sabbath (flirting, kissing, generally getting all up close and personal), and in Sometime Never, Sabbath actually admits he's "more than a little fond of" the Doctor. (Aww.) Well, with the Master gone, the Doctor clearly needs a recurring Friendly Enemy to have sexual tension with, right? More on the Doctor Who Foe Yay page. It seems like Lloyd Rose likes this trope, since in City of the Dead, one of the villains is a Mad Artist who makes a bit of a fuss over the Doctor's attractiveness, and another one who... well.
'[...]You're my key. Or my bait. Probably both. But in either case -' he traced a forefinger along the Doctor's long upper lip - 'you're all mine.'
The Doctor twisted away but Dupre tightened his grip, holding him still. 'You can't get free,' he said softly. 'I've made very sure of that.' He slid his hand down to the Doctor's chest.
The Doctor was "more than friends" with Alan Turing and mentions having been in love with William Shakespeare.
The Doctor has a sometimes-tempestuous, sometimes-adorable relationship in The Year of Intelligent Tigers with composer Karl Sadeghi. Karl spends most of the book being very obliquely in love with him, waxing poetic about the Doctor constantly*
Karl watched the Doctor doze. He had flopped back on to the soft grass, his golden-brown hair spreading around his face. The bright sunshine highlighted the exotic whiteness of his skin.
*
The numen had left the Doctor: he was no longer a god of thunder, but only a beautiful man lying in the grass.
Fitz and the Doctor act Like an Old Married Couple, and Fitz admits to the fact he loves the Doctor and might like to have sex with him. Given the Doctor occasionally flirts with Fitz*
Fitz gaped. ‘A sailor? I don’t believe it. Go on, give us a jig!’ The Doctor laughed. ‘Not likely – but I’ll show you my tattoo if you’re lucky.’
Jerkass Woobie: Some pretty awful things happen to Compassion. For example, she turns into a TARDIS, and just to make it worse the Time Lords try to capture her for "breeding purposes". Whenever Fitz or the Doctor tries to show her any sympathy, she doesn't take it well.
Just Here for Godzilla: In the fandom, The Taint is almost universally panned as a sub-par book that's only saving grace is introducing the reader to Fitz Kreiner. It's often advised to new fans to just skim until you see his name, then read those bits.
Memetic Outfit: Fitz often wears leather coats, which is probably mentioned more often in Fanon than in canon.
Stoic Woobie: The Doctor's life is basically terrible, in case previous entries in his trope list haven't already made this clear. He's rarely seen crying about it. Very rarely. Possibly only in Halflife, in which it was quite obviously helped along by the fact he was still somewhat under the influence of swapping minds with Fitz, who's significantly more emotive, and it was appropriately manlyTears of Remorse, at any rate.
He must spend half his time stuffing them into their uniforms and trying to stop them from climbing things and crapping everywhere
, his apparent inability to pick a pseudonym that doesn't have to do with holidays or days of the week, etc. It's just that he reaches a point of being no more menacing than any other character.
Fitz Kreiner. He was peer pressured into smoking to prove he's not some kind of rule-abiding Nazi (he's now addicted to nicotine), and worried about "getting his head kicked in" when he was three. There's a poem about it. It's almost like every EDA he's in is required to add another reason (or five) to why Fitz should be a horrible, cynical, broken person. The fact he's not is absolutely astonishing.
