not really? i find them to be too bland/tropey, i just mainly enjoy the interactions sheldon has with some of them... i tend to focus on characters that resonate with me emotionally, every other character will probably just be "ok" to me so i'll provide my thoughts on their sheldon-adjacent dynamics instead

brad and sheldon can be kinda fun with how laid-back brad is as opposed to sheldon's usual jitteriness and i sometimes like imagining them having casual sex... but i really don't appreciate how the fandom wants to pair them as if to "fix" sheldon's emotional dependency with jenny, brad sucks as sheldon's friend as much as jenny does because he really doesn't try to understand and accept sheldon and often shrugs him off as "weird"

sheldon being "brotherly" with tuck in the "pain in my sidekick" episode was really sweet because it shows how eager sheldon is to care for others... other than that tuck is just kinda there being a dumb little shit and aside from this one cute interaction i'm not interested in seeing him with sheldon

with nora sheldon clearly looks up to her confident motherly scientist persona and they make a pretty fun team of two, i can even see how she could take him under her wing for personal reasons... but that's as much as i can say about her

vexus is literally just a sexy human-enslaving bug?-robot? queen, she was able to swindle sheldon emotionally once to steal jenny's blueprints from him by appearing as an innocent robot girl in need of help so sheldon's loneliness expectedly makes him cave in and even start wanting to bond with her... she could definitely make him her human pet but jenny already succeeds at doing just that and quite well too lol

so basically... i kinda only want to explore sheldon's character in a mostly isolated manner, rarely adding in jenny for specific emotional effects and even more rarely adding brad, usually together with jenny, but i have almost no interest in mlaatr character's aside from sheldon at this point
