Sequel to 'Holding on, or letting go'. Lexie has not coped well with change. Mark and Callie are still happy but people are starting to choose sides and Seattle Grace only works if all its parts work together like a machine. All its parts are not united.

Mainly Mallie and those that primarily surround them. They're in trouble, how does this affect the Seattle Grace machine? Set after 6x05 but not including the mercy westers or subsequent storylines.
