Jason's Links
Honestly, the most Jason feels about his fellow crewmate is disdain. After finding out that Fletcher killed his best friend, the red spaceman did everything he could to make his life terrible.
There are no surprises anywhere, Fletcher quite hates the man who was best friends with his brother. He normally refuses to talk to Jason so the two don't really know each other at all.
His best friend! Jason certainly cares about Matthew a heck of a lot, and perhaps has some secret hidden feelings for him?
Not that he would ever tell, though!
They are co-workers, first and foremost, or at least they were supposed to be until Matthew nearly killed everyone.
His best friend! Or... Should that technically be former best friend? Not that Matthew really knows. When he had his memories, the two would talk about so much, and the Security Manager treated the Guard like his brother or something.
Without his memories, Matthew has no opinions of Jason, he doesn't even know him.
Jason treats the teenager like she was his own daughter. He clearly cares about her so much, considering how he was willing to look after her while on the Skeld without her father, and if he could he would adopt her so she didn't have to be stuck with her mother forever.
Lindsey feels like her father's best friend is a stand-in dad for her, she sure loves being around him when her own father isn't around, and he clearly understands her feelings. She wishes he could be looking after her currently, and not her own mother.
