#4. What's going on with Dean Ambrose?

Last week, Drew McIntyre wanted an opportunity and confronted Triple H. Dean Ambrose came out and provoked him, leading to a match between the two. Surprisingly enough, McIntyre somewhat squashed Ambrose in no time, finishing him with not one, but two Claymore Kicks.
After the match, Seth Rollins was backstage minding his own business when Ambrose came to ask where he was, as if it was pre-October when they were still allies. Rollins asked what was wrong with him and Ambrose shrugged and walked away.

He seems to have forgotten the events that happened over the last few months. The prior week, he wished Rollins luck against Brock Lesnar. Is he officially turning face for good as his contract comes to an end? What is going on with Ambrose and his memory?
