Lancelot flits between letting people in, handing people drinks and trying to variously rescue people from Lily and Lily from other people. He hadn't expected Arthur to come, in truth, the man was a little standoffish, but the fact that he has is a pleasant surprise. He grins as he finally loops back for Arthur, reaches out to pull him into a quick hug.

You can't escape the hug, it's a normal sort of greeting for Lancelot.

"I wasn't sure you'd come -- please, let me get you a drink! Beer, punch, something stronger?"

He pulls back and Lily bounces around their feet, tail swishing up over her back. Hello, hello new person! What is going on? Are you here to play too? She lifts her front paws and drops them repeatedly, desperately fighting the urge to jump up but wanting greet Arthur. He is so tall, so high! Can he not come down so she can say hello?
