This is a copy and paste theory from another thread

Summer and Cinder knew each other (possibly they were student-mentor or Summer was someone Cinder looked up to) and the Schnees are somehow directly involved in Summer's death, leading her to join the White Fang and sabatoge the SDC. And maybe the reason she was in the hallway in episode 2 was because she was looking for Weiss, but Ruby caught her before she could.

Still haven't figured out where Spring comes in, but someone thought it could be Yang's mother.
