Having two sets of grandparents is confusing enough, but it's confounded by Ana's inability to differentiate between the words "grandpa" and "grandma". So we've got "grampa" (grandpa McGrath), "grampa" (grandma McGrath), "grampa" (grandpa Loeppky), and finally, "grampa" (grandma Loeppky). She loves them all: they're all grampa to her.
