Keep an old pillowcase in your pocket and if you think Scar is being neglected again slip him into the pillowcase, into a pocket or bag, and out. If you can't keep him he's better off released, if you can keep him that's fine too.
It sounds to me like he needs to be observed closely enough that a shed shouldn't be a surprise, the only one of mine that ever surprises me is the albino because he eyes don't go blue and the colour change in her eyes is very subtle. If you're looking at a snake every day you don't miss an impending shed.
