The more I look at those photos I think Snow does shoot Charming with an arrow and he gets captured, but she feels bad about it/realises she’s done wrong (watching from behind the tree). So she goes to rescue/help him later in the evening as he’s tied to a tree.

This is just gunna break my heart, ‘cause he’s gunna be all ‘Snow I love you’ and she wont even remember him. And Charming will be all sadface and Snow will be confused and it’s just gunna be a basket of emotions isn’t it.
