Thinking abt tf2's comedy writing and character dynamics bear with me... all three canon "pairs" of characters - Medic and Heavy, Soldier, and Demo, Sniper and Spy - have a similar dynamic, a wacky comedic character and a more "straight-man" type of character. Medic and Heavy are probably the example of this people are most familiar with reading and writing this way, but I can argue the case for the other two too! Medic probably does the most absurd things out of any tf2 character, while Heavy is considered one of the most down-to-earth members of the cast and serves to "ground" Medic in reality a little bit; the best example of this in the main comic is, of course, the baboon pregnancy bit, and I would also consider all their dialogue in Meet the Medic to be very representative of this dynamic. People tend to characterize Demo as basically like. "Soldier 2" which I think is slightly accurate but not completely representative of him! While Demo is a very Big personality, very memorable, very bombastic (lol), he DEFINITELY works to ground Soldier if only in that he's actually smart. In the main comic, we see this when Demo is reassuring Soldier he won't be fooled by his civilian disguise, and in the update comics I think this is best shown in the WAR! comic, where Demo has his life together and has a nice ass house and is taking care of his mom n everything, while Soldier is living in the dark surrounded by army surplus tomato soup and boxes from The Rib Place. Now I know Sniper and Spy are going to be a hard sell, because Sniper is not as outwardly Wacky or Silly a character as Medic or Soldier, however he's pretty obviously grounded by Spy in the same way Heavy and Demo ground their partners. Spy is so uptight he's basically begging to be a comedic straight-man, and his repeated displays of disgust towards Sniper's more outlandish and comedic behavior gives him that outlet. Jarate is the most obvious example of this being their dynamic, but I also think the part in the comic where Spy is exceedingly disgusted by Sniper's nudity and yet refuses to give up his very expensive suit jacket counts towards this (in general, having a clothed character react strongly to a naked character's nudity is what keeps the repeated use of nudity in the tf2 comics funny, imo). Theirs is a liiiittle bit different tho, since in the process of "grounding" Sniper, Spy is also performing one of his own signature jokes (thinking he's hot fuckin shit when he's really no better shakes than anyone else in his situation)
