Nah, Mike was telling him he needs to 'wake up' this episode. So, Cooper is still somewhere underneath, and phrasing it as 'wake up' implies that when he reappears it will be somewhat sudden, rather than a gradual piecing together. He has made essentially no progress since appearing in that house with Jade, he's only collected more phrases that people have said to him and apparently he remembers everything since then as normal (like how he was so happy to see a picture of Jade), but I don't think he's any closer to being Cooper than he was when he first appeared. So I think when that happens, it'll be something that sets it off.
