I am inclined to agree. A gut eeling tells me all of them are connected somehow. Here is a theory, but I want to remind everyone that is it JUST A THEORY!

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.

Again, just a theory.
