What should I do here?

can he dribble after coming back in? thanks

It depends. If he established player control while saving the ball, then throwing the ball back in-bounds is the same as starting a dribble. Iow, when he then comes back in bounds, he can continue dribbling. He can't come back in, grab the ball with both hands(ending his first dribble), and then dribble again. That's an illegal second dribble. This should be in the cited case play above iirc.
