1) Russell considers Ed a very good friend, even though he doesn't refer to him that way (because he's never had many friends before).
2) Russell's first kiss was with a girl named Olivia (she was two years older than him) back when he was still living in Xenotime under the name Edward Elric. She cornered him by the shed where he had been reparing some farming tools for her father. He thinks she only did it because she thought he was some famous alchemist because, once she found out the truth, he never saw her again (he still feels guilty about lying to her).
3) This led him to think that girls will only like him if he's famous (he doesn't have time for girls anyway).
4) Fletcher is the only one that can take care of Russell even though Russell tells him not to worry (somtimes he does need to be taken care of). If it wasn't for his brother, Russell would probably forget to eat sometimes.
5) Russell knows it's easier to let Fletcher take care of him (even though he's the one who's supposed to be taking care of Fletcher).
6) Russell was inspired by Edward Elric and has since been studying to become a state alchemist (he's not doing it for himself but only for his brother). Once he's a state alchemist, he's sure things will be much more stable for them.
7) Russell needs to learn how to slow down once and while, because once he sets his mind to a task, he won't stop until it is sucessfully finished. This is especially unfortunate for him when a project is not going well, but Russell hides his stress from others and works through it (Fletcher is the only one who isn't fooled by this act).
8) When they moved to central, Russell imediately turned their little living room into THE LAB (Russell spends most of time locked inside).
9) Russell has a hard time admiting things to people (especially those that he looks up to) so he hides his fear and sadness but, as hard as he tries, he can never cover up his anger.
10) He was eleven when his father left and it was the only time he's ever cried in front of another person (and his mother held him tight and sung him a lullaby from when he was younger). He never let himself break down like that again.
11) He was thirteen when his mother died and Russell sat in silence for an entire day (until Fletcher came to find him and he remembered his new responsibility).
12) Russell doesn't hate is father for leaving (he just doesn't want to let him down).
13) Sometimes he wants to just get up and walk away from it all (and immediately feels guilty for even thinking about it).
14) Russell loves cats (he's never told this to anyone) and when Fletcher adopted a small one and named it Puffy, Russell really didn't mind when it sometimes slept on his pillow.
15) His mother used to have him and Fletcher help her in the garden everyday since he was five (Russell loves the smell of dirt). For some reason, roses never grew in their yard until Russell started using alchemy to help them along. He grateful to her for teaching him about plants.
16) Russell has turned smugness into an art form (even though that's not who he really is) also making it something to hide behind if he needs to.
17) His middle name is Nash (a name to live up to) but he's never found the need to tell anyone about it.
