awesome! i could see kloie and her mom fleeing to california to be closer to ~osher and the rest of the family right after meredith's passing, so maybe that caused some strain between she and sam? i don't wanna step on anyone's toes, just a suggestion. i mean, we could always just wing the reason for the separation. i can also see sam being "the cool dad" who she still keeps in touch with and who she is very close to!
