It appears S2 will be safe for the night. X is being an @ss. I am p!ssed off and probably a little tending towards irrational emotionally highjacked right now. How dare he!!
Ok, that’s not helpful. Sorry.
When you get S2 back that’s it. No more visits. X lied. And then has some vague plan of getting S2 back to you. Speak to your lawyer and get this arrangement nailed down. Use a third party. X’s behaviour has consequences; he has lost the privilege of a cordial drop off and pick up. Trust is a fleeting thing. He has lots of work to do to regain your’s again. (Dang, what a goof that guy is)
Unfortunately, it is probably going to need to be letter of the law for a while. No last minute alterations for visiting. He can give up his time, but doesn’t get it back. Playing hardball is appropriate at times. I think (or maybe feel right now) that this is one of those times.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
