ngl it’s pretty annoying to me when the response to any female character existing in proximity to a mlm ship (canon or not) is either “boo she sucks I don’t want her to be a love interest and get in the way” or “don’t worry she’s their mean lesbian bestie” like have you tried being normal about women for once
tired: the smart, sassy, motherly, ultracompetent girl cleverly arranges for the two boys to get together
wired: the two boys get together by desperately trying to fix at least one of the many, many things that are wrong with this hilarious disaster of a woman (they fail)
she’s really mostly a “funny to bump into you at this conference” to their relationship than anything else. like 99% of how they feel about each other is based on their PRE-EXISTING RELATIONSHIP. they were friends and they bought thought the other betrayed them and they care and they have a rivalry and Agatha is really mostly just like. a setting. like sometimes they bond over her and sometimes they compete over her and sometimes she brings out the best in them and sometimes she brings out the worst in them. she also cares but mostly is busy with her own stuff. she also sees their vastly overcomplicated relationship and couldn’t give less of a shit so long as they’re not killing each other / sabotaging her.
it’s a FANTASTIC dynamic
(like, it’s incorrect to say that “their rivalry over her” is what “forced them together”! them both having someting to do with her is what caused them to run into each other! they found their way towards being together from there based purely on being each other in each other’s vicinity! Agatha was a convenient stoplight for them to be stuck at! their rivalry is not even particularly over her! they care about her and each other too much to really do romantic rivalry with any degree of investment)
