[See, Shaw knows that his Spatzi loves the professor and that the professor loves him in return. It's all very sweet and unexpected because really, Shaw hadn't thought Lehnsherr had it in him. Or, to be more precise, he'd been trying to get Lehnsherr not to have it in him, to see what it would take to mold the boy into someone Shaw could use - or, at the very least, get a decent amount of entertainment out of before kicking the bucket. But that's okay because Shaw doesn't mind surprises and he certainly doesn't mind a leverage against the man.

Shaw is particularly enamored of the name Spatzi. A poor little bird he'd found, barely old enough to fly on its own. He likely would have been killed had Shaw not stepped in and to be honest he found himself awfully fond of the boy. So, Spatzi, his little sparrow.]

Spatzi, please calm yourself. It's perfectly alright if you don't trust me but there's no need to be so demanding about it. [Still, he stands and adjusts his suit with a kindly, understanding look.] Let's talk about this. Walk with me.

[Completely unheeding of the weapon in Erik's hands, Shaw walks past the other mutant and out the door of his study. His expectation is that Erik will follow. He does not look behind himself to see if that's the case.]

He isn't harmed. I haven't touched him, just like I promised I wouldn't, and he's in the same state of health he was the last time you visited him. Besides, I'd rather not have to hurt either of you. I really do hate having to lift a finger against our kind.
