Yeahhhh the theories that Emma was actually Mal's biological daughter and she and Lily switched places got a little crazy. (I never heard the Ingrid one though!)

So yeah, it looks like Merida is just going to be thrown in directly from Dunbroch with no direct connections involved. I would say she will be Snow's archery teacher (i guess that depends on age though) and/or will just be heavily involved in Emma going good because of their similar stories with moms (like how Elsa was involved in Emma accepting her powers)
