For a while, both parties involved were silent, Ron and Dean both looked towards Harry, unsure of what to do in this situation.
Harry looked into Villin's eyes and after five full minutes had passed, he sighed.
"To think this is the path I will follow, even I had never thought it. I swear my fealty to you, for the next thousand years." after saying this, he got on one knee and looked downwards, he seemed to be taking it very seriously.
When Dean saw Harry's actions, he also seemed convinced and took a knee, "I too, swear my fealty to you for the following thousand years."
The only one left was the green-haired Ron. He seemed to have a lot of trouble deciding what to do, even when Harry, the one person who he respected greatly, took a knee, he wasn't sure if it was the right call. Villin could see he seemed to be fighting his pride, but in the end, he too kneeled and repeated the other two's words.
