Hal asks if its cool he eats shrimp because Aquaman is atlantian; he eats shrimp too but Clark is a shrimp so its like 'this is cool right?' And clark has to sigh and be like 'yes hal, i already said it twice' (but hal wants to make sure because he so doesnt want to "kicks clarks ass" because what kind of jerk move would that be? Eat his shrimp-family and then beat him in a fight) and bruce is asking what other shrimp things he can do because like, dude he needs to account for this for missions and other things while the female league members text lois for answers to THAT forbidden information
hal is going to be absolutely insufferable, like he ends up having some shrimp for lunch and he's like "did you know this one, supes? this could be your brother for all i know, that would be awful huh" but then simultaneously look clark dead in the eyes as he eats the shrimp anyways
