From Entertainment Outlook:
It looks like Emma will have to find a way to cross the bridge safely,witch could involve the help of a mysterious Knight in shining armour. We’ve already had several references to ‘The Princess Bride’ when it comes to Hook and Emma and from the TV promo , it looks like we could have another one, as the Knight dramatically reveals his true identity by removing his helmet – revealing not her father Charming, but her true love Killian Jones – the man of honour.
Looks like that post on tumblr I found, was actually correct.
