Between Percy knowing Grog's favorite color (6), knowing that Grog was holding up one finger to him while he was blind to test his eyesight (Grog's middle finger), knowing how to win a cannon ball contest that Grog was judging (by exploding himself with raw sodium and drawing blood from both himself and Grog lol), and Grog getting Percy a broken pocket watch as a gift (because he knew Percy would enjoy tinkering with it), I genuinely think Percy and Grog's relationship is one of the most slept on in all of Critical Role.
Plus this little exchange that I love so dearly:
Percy: I know we don't always agree, and I know that I can be unkind but... you know you're family, right?
Grog: I don't know much, but I do know that.
Percy: It's nice having an older brother again.
