Maybe there is something which explains the awakening better. Cause I think he awakened cause of the activation of the tower and then he opened the door (which others couldn't).
And awakens his younger self so soon wouldn't be wise, I believe, cause that makes the time-paradox maybe more than a problem.
Although we could ask the older version how the tower works so there is no need for a long sleep. Hmmm...
But we will see.
