He is coming out from under the bed to play. That suggests that the bed is making him feel secure enough to venture out. It sounds like progress to me.
Remember, Geoffrey hasn't had as much experience with pilling as Artie had. Given time, Geoffrey will probably get better about being pilled. He spit the pill out, but he didn't slash you. He spit the pill out and went under the bed, but he came back out and let you catch him. We all know that none of us could actually catch a cat without a trap if the cat wasn't willing to be caught.
I'm glad you know what he was fed at the shelter. From your description of the timing, some visitor to the shelter must have terrified him. Do they have security cameras? Perhaps they should consider them.
The good thing is he wasn't like this at first, which means, with patience he can return to the secure guy he once was. He seems to really enjoy playing with you. That's huge.
