The art is just so beautiful and Elena is so badass, I can't. :")
@Katrina Maybe she's just being super cautious in everything, but personally, I think it has to do with her decision to obtain her revenge no matter what, so that's why she's not opening herself to anyone else in this life (that was what it caused her death in the very first place so I guess it makes sense).
She's just taking everyone useful in order to obtain her revenge, she doesn't want to become friends, she just wants loyal tools under her wing and she'll give them benefits as well. Pure business, no feelings attached (that's my thought but who knows, lol).
