Finch is a victim of non-con. Reese is there to deal with the aftermath. I will love you forever if there's loads of hurt/comfort and a tender/protective!Reese.

Reese, Finch, or Reese/Finch, either is equally wonderful.

I want, really quite badly, a fainting Finch. Reese on hand to make sure he was alright would just about leave me kissing your feet...

While Reese is undercover with the bad guys, Finch is captured. Reese is commanded to interrogate him. Reese must torture Finch, or appear to do so, else he'll be outed and they'll both be killed.

Reese ends up hooded and restrained in a abandoned building somewhere - for once he can't free himself. It's getting hard to breathe, his mouth is duct taped under the hood and he's pretty sure this could be it. But he still his ear piece and Finch manages to figure out he is in dire need of help. He keeps talking to Reese, keeping him calm, while he uses the GPS in his phone to track John down and then comes for him. Reese won't admit how badly shaken he is, but waking from a nightmare at the library he finds Finch has sat up watching him, despite how sore it's made his back, as if he was expecting the nightmare. But Finch is having his nightmare while awake, imagining if Reese had suffocated before he got there.

Can be slash if writer wishes!

The Machine(or Finch) offers Shaw the dubious choice of either Leon or Root as her new tech support?

In 2x21 Root said to Harold she wished she had a pet like John.
Somehow she gets to 'borrow' him (by threatening to harm Grace for example). John is unwilling but has to comply anyway, hoping he can go back to Harold soon.

Wouldn't mind dub-con/non-con Root/Reese, or Finch/Reese at the end.

The backwards remix of this (http://astolat.tumblr.com/post/48489637435/strange): When Harold asks John to have sex, he says yes even though he's not sexually interested in him, because it's Harold, and he wants Harold to have everything he needs or wants.

Up to the author whether John ends up liking it/falling in love with Harold or not.

Based on this gif & tumblr commentary, the one where Finch has to go undercover as (or impersonate) some sort of super evil Lex Luthor type crime lord and Reese is his creepy right hand man bodyguard/enforcer. (Andthentheyhavesex.)
