I'll second this! I feel like that NYC event was central to a lot of characters meeting for the first time.

I'll third this. The Fire Trolls were definitely tied to Arthur and it's fundamental to many of our characters meeting for the first time. Besides, J'onn's posts would especially get a bit wonky if suddenly Arthur was snapped out of existence.

I'll have J'onn drop off the kids with Arthur's dad then go on to help with the survivors, giving space for them to fade into the background, perhaps to be taken up again if Bounce is ever able to come back and wants to do so.
