I think it's wonderful you are continuing to give Jackson the time he needs to settle in and I know everyone here has experienced that itch to handle a new snake....for me it's the hardest part of getting a new snake!
If I learn nothing else about royals I've learned that patience and routines are just such good things. With Brannagh we're seeing a lessening of her aggressiveness, with Saorise we're seeing a continuing acceptance of humans and a lessening of her defensive balling up. With both these females it's been all about fear I think, though they express it at opposite ends of the spectrum. Just being patient and doing the same routines with them, time after time, every time we interact with them is showing some nice results for these pretty ladies.
Gotta love the snakes and the life lessons they offer.
