Sort of going off of what @mrsmarymorstan and I were posting about the other day.
John has no idea how to cope with Jason.
Because Dick and Bruce? They will absolutely flirt right back when he gets going. Especially Bruce. It freaks the hell out of all the rest of the League because here’s this scrawny Brit who looks like he woke up under a pool table after a three day bender (he did) and smells like he smoked an entire pack of cigarettes before lunch (he did), and not only has Spooky not turned his face inside out for suggesting they go back to the Batcave for a bit of slap and tickle, they all just saw Batman blush and bite his lip and make a smutty joke right back and Green Arrow thinks he might be having a stroke. Dick’s not quite on Bruce’s level, but he still won’t hesitate from bending over and arching his back a bit to get John’s attention if necessary.
So with Jason, John’s brain goes ‘Adult Bat? Very dangerous? Magical elements? Big blue eyes and a face I could make myself comfy on? Sign me the fuck up.’ and he sidles on up next to him and asks if his jaw ever aches when he thinks about him after that little incident where he climbed inside his mouth.
Which is how he woke up in the Watchtower infirmary with three broken ribs, a fractured ulna, and a flinch whenever he sees red.
