I have read too many simarkus fics where Simon is this big blushy mess who can't handle even the slightest flirting and casts his eyes down when Markus looks at him and can't like function if Markus is near him. No no. It would be so difficult to embarrass Simon or throw him off balance.

Markus fell into Jericho and immediately said "damn bitch u live like this" to which Simon smoothly replied "my bad lemme book wanted and hunted deviants a nice private 5 star hotel I'm sure that'd be safer, asshole" and moved on. Simon stared at Markus in the eyes on Stratford Tower, gun pointed to his head, and said "there's always a choice." Simon repeatedly got in between Josh and North's disputes. Simon was hugged so tenderly by Markus and hugged him back, full force. Simon at times expressed cynicism to rival North's. Simon heard Markus start singing as they were all rounded up and held at gunpoint and looked at him like "wow this bitch really is stupid". Simon gets mad if Markus fails to take down the drone during Spare Parts and falls because Simon tries to help him up but Markus brushes him off. Simon looks Markus in the eyes and says "ur literally our only hope lol good luck with that pressure", and then when Markus walks off Simon's face is like "my God he's really our only hope. We are maybe doomed". Simon actively Doesn't Say Shit when Markus makes a decision but will demand Markus leave the freedom march to preserve lives with no hesitation. Simon reminded Markus to hide his face during the Stratford speech. If Markus chooses to kill the Stratford guards and gets Simon shot he's all like "yeah no I'm fine, fuck you". Simon took one look at a shot and fallen North on their way off Jericho and said "it's too late for her Markus we gotta leave her and gtfo" and then proceeds to get mad if Markus actually does leave her behind. Simon fights like a ballerina and doesn't hesitate to vault off of humans or kill to protect. Simon is a capable bitch and I love him.
