if youβre looking for bromance/homoerotic moments that is mostly coming from dick and roy. for them iβd read outsiders (2003). thatβs the holy grail of their gay interactions imo. i also really enjoy action comics (1938) #613-616 and #627-634. batman plus arsenal only features dick at the beginning but roy does yell at bruce for being a shitty father and also itβs just a really good comic so that is worth a read as well.
with dick and wally their moments together post ntt are a bit more scattered across comics. dick appears a few times in the flash (1987), most notably issues #81-83, #142 (heβs the best man at wallyβs wedding π₯Ή), #159 (best man pt 2 electric boogaloo), #210-211, and #214-215.
of course the real og, the place where it all began, is teen titans (1966). thereβs also a very recent limited series called worldβs finest: teen titans (2023) with the og titans crew. i havenβt read all of it and some parts are definitely cringey in the way that gen z characters written by boomers can be but mark waid is a good writer so i forgive him.
