Granny (Beverley Elliott) and Ruby began the episode by building a cage for Ruby, but she turned into a wolf and broke out.
Even worse, it appeared that she killed Billy the mechanic, though that ended up being Albert Spencer/King George's (Alan Dale) doing. Fortunately, David Nolan/Prince Charming (Josh Dallas) figured it out and discovered George had Red's cloak in time to save Ruby from the mob, and help her transform back before she hurt anyone — though it turns out Ruby can actually control the wolf herself.
So Ruby does transform in Storybrooke, but it looks like she won't end up hurting anyone because of it.
