After The credits (spoiler warning)

[The Caped Knight]

Apparently from what I've heard, there seems to be another scene after the credits of the movie.

Now here is the problem. I never saw the scene and I really want to know what happened. Could someone please do me a favour and give me a short breakdown of exactly what happened? Thank you!

a man in a hospital bed awakening from a comatose state. The scene is the pay off to a sequence that is set up early in the film while Professor Xavier gives a lecture on the ethics on the misuse of mutant powers. In the hidden scene, the man awakes from his comatose state and calls out to Dr. MacTaggert using Xavier's voice. Dr. MacTaggert replies, "Charles is that you?”.

Did Moria ever work with Dr. Essex? or had anything to do with him?
