Ben goes to tell Grandpa about the missing transformations. He tracks them down. The closest is Echo Echo. Ben starts losing himself. He transforms into Big Chill and disappears. He gets control back. He sees the Echo Echos. Jenny over the com tells him to set the Omnitrix to capture mode to get the aliens back. The Echo Echos fight Ben. He breathes Ice on them. They start multiplying. He keeps freezing them. They finally stop. Ben captures them back. He checks and sees he has access to the form again. Grandpa examines the watch and tells Ben that the aliens can control Ben if he takes the Omnitrix to lightly. With that Ben focused and turned into Big Chill. For the entire time he didn't have problems.
