My only concern with Emma conjuring knight Killian up for magical purposes, is I’m pretty sure Killy revealed himself as the knight, during a night scene… Or am I remembering it wrong? The only way I can think of it all fitting together is maybe Emma & Regina are stuck out there for literally hrs, while Emma is trying to learn magic Regina/Rumple’s way, it isnt going well & as darkness falls, Emma uses her love as strength- rather than hate/negative emotions & that’s how Snowing find out Henry thinks they are ‘boring’- because he’d rather stay with Killian until Emma returns, but Killian has something else he has to do & cant watch him until Emma is finished (maybe he Ariel has asked him to help again in SB & thats how he & WW end up meeting- or WW ‘stops by’ looking for Henry (to get to Regina) & thats how Hook meets her).
