Lake loves his older sister River, whenever he can and whenever the opportunity arises he surprises her with surprise hugs, this time he caught her while she took care of little Lucy at Oasis. A moment of family fun.

NOTE: I still don't know if Lucy will be the youngest sister of the trio or a future daughter for River ... but more inclined to think about the second option, I need to find a candidate for a father yet XD
