Luke was hugging Simeon 2 years before you left Devildom and he felt so flustered he changed to his original form (theory: he was cursed into looking young and once he finds the right one he's back to normal)

When you came back to Devildom you saw everyone but Simeon was holding a little angel baby (They didn't do IT together they created kids from emotions like Lucifer) Simeon smiles at you as Luke walked up to you with 4 more little angels
