It's not Jack's fault, that it's a bundle of nerves. There's some corner of its brain that registers this, but it's in a strange place, with strangers who don't react like it expects to even something so fundamental as what it is. Getting mad isn't the right reaction to all of that, but it can't afford the other reactions right now.

So, as it walks past Jack, it's keeping its transformed arm curled up where it's less visible against the dark fabric of its jacket.

"Whatever," it says in parting. It doesn't look sure of where it's going, only that it is going.
