Bart starts asking Wally sort of awkward and vague questions about his relationship with Artemis.
Wally gets all cheeky and proud because his baby cousin is crushing so hard on a girl oh my god! He answers everything with pride because Bart is coming to him after all.
Bart starts asking questions about sex.
Wally slowly realizes some of these questions definitely don’t relate to people with vaginas. Wally silently screams because he realizes Bart is interested in a guy and asking about sex with a guy and holyfuckingshit!
Wally quickly sends Bart off in Dick’s direction grumbling about how he definitely knows more about this shit than I do.
All the while Jaime dies of embarrassment in the background.
