"That's far enough, children. The adult is speaking now," He spoke calmly into the silence. His stance remaining commanding and in control. Right arm tucked behind his back while his left swung over to cup Billy's unresponsive chin. The Doctor didn't see the need to keep his eyes on them.

"And it would benefit you to listen instead of barging in guns ablaze. You'll notice we did not exactly hinder your approach yes?" He wasn't actually happy about Gambit's decision, but best to make it seem like a calculated effort. The rescue team wouldn't know the difference. "My interest is in the Scarlet Witch. Her child, while certainly facinating, is not my goal this day."
He grinned and turned his head toward the too, grip on Billy's chin tightening just a touch as he allowed the boy's mind to return to reality. "We've been getting to know each other, going over notes about the Cube."
