ok look im sorry for the cringe but i legit canNOT stop thinking about G-Man and GLaDOS as a couple and them tryin to work it all out despite complications
GLaD's boyfriend is some guy who looks like a 50 y/o human business man and him working so close with humans doesnt make it better but on the inside he really does only look human when he can do so much more than they can and hes disposed of humans like trash before but hes clearly changed and it gets confusing
G's girlfriend is a murderous AI woman that while she has a genuine drive for science she sometimes uses it as an excuse to kill large numbers of humans for her own personal gain and ego and its difficult to be dating someone who thinks so unbelievably little of humans when you legit look so much like one
but they mostly work it out because they like to see how far humans can push their own limits to reach a goal even if its not that rewarding and they can also observe them for future reference on how to treat them for better or for worse, and they get a kick out of talking shit and slappin people around and idk about you man but that seems like love to me
