hiriluk died on chopper yes, but chopper had support through that grief. luffy had emotionally stunted ace and dadan LMAO doctorine isnt the most emotionally intelligent but well. she's very experienced and was able to "fill" the void left by hiriluk

on the other hand, luffy and ace spent a LONG time instinctively looking for sabo, turning towards him during training and arguments and *everything* dadan's a fucking mountain bandit, makino doesnt see them often, chief doesnt really care
