Ik it's been talked about before, but the fact that Macaque thinks Wukong killed (and that he was about to again in season 3 when he was literally choking him) him but he still helps him when he can and smiles softly at him and goes out of his way to see him and stares in awe when he sees him coming to help MK and still accepts his peach offer (symbolism for rekindling friendship) and smiles when Wukong says "we" instead of "I" and gets sad when he sees the memory and realizes he wants to rekindle their relationship and crashes a beach party just so he could be with him and then we have season 5 with him looking genuinely scared about Wukong getting hurt.
