ECDYSIS question: If roles were switched a bit, and this was Pitch we focused on, would Tallulah and Anton have tried to help out or would they have gone for reinforcements?
This is an excellent question! While Tallulah is tuned in to both twins, I see Anton, as both more geographically [he lives in Boston and in Paris, rather than New York] and emotionally more distant from Pitch.
If Pitch were the one needing an advisor to the lovelorn [aka his breakup with Pitchiner], I think Tallulah would take point on trying to cheer up Pitch, but she'd eventually call in Pitch's godparents, Gilen and Annelle. Those two might sweep Pitch off to Europe, rather than what happens with Piki in New York City.
I can see Pitch's godparents giving him some kind of European Grand Tour... Vienna, Italy, Brittany, Hamburg... as a way to get his mind off Coz. It might half-succeed, but Pitch would still miss his big oaf and want to show him the highlights.
Eventually Pitch would just want to come back to the States and just wait for Coz to get back from Afghanistan. And his godparents will understand.
