The ship shined red sunlight on him and kept it fixed on him so that he could be injected and so he didn't burn through the sedative.

And he did need the sedative because he didn't stop fighting when the tentacles came, trying to throw them off with his telekinesis, and then just trying to pull his arms free through sheer force of will alone when the red light dampened his powers.

"You can't do this! You can't! You...you..."

His eyes rolled back into his head and then he was out, drugged like the others, the red light fixed on him so he stayed that way.
