He led them down the long corridor for several minutes before stopping in front of, well, a long expanse of wall. A small portion of it, seamless otherwise, slid to one side and he stepped through, leading the two into an observation room. It looked much like the Danger Room's control room: a bank of computer terminals topped with a glass or glass-like material that looked out into an open space.
A capsule to one side housed a sleeping baby. Sinister smiled and put a finger to his mouth, indicating the two should be quiet before opening the capsule and gently lifting the child - who couldn't possibly be more than three months old - out of it. The babe stirred and yawned and the doctor, shushed it with soothing coo's while walking with a slight bounce to rock the child. He left the control room and entered the other chamber. The floor morphed, creating a highchair of white metal in the center of the room where Sinister placed the child.
He leaned over and soothed back to sleep before summoning a large swath of material. It floated across the room from a secluded side chamber and he set it up around the baby, making sure no seams were left unsealed. Then he calmly turned around and re-entered the control booth.
