Konstantin does notice how Arthur tethers himself more tightly to his companion; they're certainly very close. Again, this is such an odd thought, but... He's very willing to help. God knows how much Arthur has helped him.

So he smiles brightly as John agrees, and offers an encouraging nod.

"Consider it done! I'm sure you could use some time to settle in, rest up, but as soon as you'd like, we can start. We can meet here in the Community Center, or at your and Arthur's home — since I'm assuming you'll be staying together."

He smiles again, starting to feel genuinely excited about this?? He can even bring healthy snacks...
