In the BBQ poster/pic of Once, Henry is wearing the same blue scarf thing that Bae was wearing in S01E18 (I think it was E18- the ep where rumple turns the egg guy into a snail & stands on him). H&K said there is an Easter egg as to who Henry's father is hidden on/in the pic of Henry & it isnt the bow & arrows- I'm hoping its the trunk he's standing on rather than clothing or what ever is hidden in the bow bag 😉
Wait-Henry is shown in that pic holding bows and arrows! His dad is Robin Hood! 😮
