Wally was paying attention to Dick talking, keyword, was, then you walked in the Titans Tower after patrol, his childhood friend, and Dicks current partner...
Wally liked you before Dick did, years before actually, he was the one who introduced you to the Titans when you joined, introduced you to his best friend Dick, biggest mistake in his life, Dick immediately hit on you and you two hit it off. Why! Wally was pissed, Dick was whining about wanting Kory back just days before he met you!
Back to now, It's been two weeks of you and Dick dating, and Wally hates how he gushed over you, held you, kissed you, that should be Wally, not Dick. Wally should be with you. Not. Him.
Wally tried not to glare as Dick immediately rushed to hug you, kissing your forehead.
"Get a room!"
Wally called out, trying to be funny to hide his jealousy.
