Hello!

A corn snake was recently put into my care and I've noticed a couple off things

1. He is in shed, but seems to prefer hiding through the whole process. Is that normal?
2. I just did a quick handling session and noticed that I can hear the occasional clicking sound from him. I read on another forum that it might be his shed skin coming out of place, or his jaw relining. However, some say it's the start of an RI. It leaves me worried.
3. He has a mysterious big brown spot on his face that looks like a scab. I'm not well-versed and how reptiles heal, so I'm wondering if I should be worrying about it or not. He seems to be acting normal despite the spot. Here's a picture. Don't worry about the white, I'm 90% sure that it's just the shed skin around it trying to come off.
