anyways i think bruce historically takes the batboys on an annual fishing trip which they all hate so so so much. it gets to the point where it's only tim accompanying him, because unlike dick or jason, tim would simply disintegrate from guilt if he stayed home.
then cass comes along and bruce thinks "oh no well there goes my fishing trips. all of the boys hate them anyways... and it's not like i can take a GIRL fishing."
cue bruce and cass, alone next to some dinky old river with nothing but their fishing rods and an esky full of cold beers, wearing a matching pair of fuckass fishing hats, both religiously applying sunscreen and bug spray.
