HEHE... yes I do, in fact- i even have an entire google doc about all their interactions and connections to other characters if you are also interested:
i go into wayyyyy way way more detail about them there. HOWEVER!! for this i will just go through my all-time favs
This one is obvious, it's their first direct interaction on-screen in the game, and it also implies that Sans and Alphys know each other from something that they would rather keep a secret (based on the fact that Alphys gets nervous and Sans deflects with "doesn't everybody?" when questioned by Papyrus). Also, I love that Alphys knew Sans was going to make that exact joke and she said it before him... cuties
lovelovelove this dialogue because it implies sans may know about the amalgamates (theres also other stuff like the dog food that papyrus "recognizes" from sans's room, and the chips in the skelebros' fridgs that are also in the true lab).
this one is just so silly
QUEENALPHYSQUEEN ALPHYS QUEUN ALPHYS. "at least sans is still here. he's... he's a good guy. and with him around..."
sans doing a fortnite dance and alphys calling him cringe
a gag from the tumblr ut q&a where everyone tags along to alphys and undyne's date and alphys tells him not to bring ketchup-flavored chips
sans talking about how alphys gets super into whatever thing shes currently fixated on and it's all she can talk about (x-box exclusive dialogue i think?? same with the next one)
sans talking about how alphys made mettaton out of energy drink cans (also confirming he knew her from before she became the royal scientist)
and there's a couple more but if you wanna see it you must defeat my 7 evil google docs and read my insane ramblings ok BYEEE
