Ok, why do all seem to assume spy and doc is a thing already?
How are they not a couple? Right after spy telling doc ab the tropical island dream, which is a good thing with no draw back for doc, doc just told her "i'm gonna sleep with some guy." If doc is together with spy, and is also a cheater, why would she mention it at that moment? It's more like she felt terrible because this cutie is risking her life for her and use that as a way to say "stay away", then when spy got all hurt, doc finally decided to speak her mind, but she was a tsun, so she spun her last statement into a clumsy way of saying "Please be more careful w your mission, also I miss you."
Spy might be going after doc, while doc is like "your job is too dangerous, i dont wanna moan anyone while im still young." Clearly doc likes spy, but she might also be someone who has lost her beloved(s) and doesn't want to get in a serious relationship again.
With all that said, truth is this is a badly written short. Spy is talking about their future as a couple, but doc acts as if they aren't in a relationship at all, this clearly contradicts. Also their faces are so similar and it annoys me.
