I know a lot of people headcannon Ben and Rook confessing their love for each other in like a stressful situation, or when one of them almost dies
But I headcannon the situation as like Ben getting out of some surgery (I'm thinking like wisdom teeth or appendix). And he's still loopy on anesthesia and pain meds
He then starts openly hitting on rook. Like saying how good looking rook is and saying some really raunchy stuff. And rook cannot stop blushing, he can’t believe ben in saying this type of stuff. And rook absolutely films it
rook then goes to see ben later and shows him the video and asks him if he really feels that way. Ben is super hesitant to answer, but rook tells him "I feel the same way for you." That's when they both find out they have a thing for each other
