After hearing the announcement, Uther was at first planning on returning to his dorm when he heard voices that were familiar to him and others that were new. Curious, he listened in closely to what the group were discussing and found out about their plan to look for the missing student. He wanted to help them but he felt completely nervous about asking. Thinking that it would be awkward for some kid to walk up to them and say "Hey! Mind if I join you guys?!" 

Wait... Uther realized he accidentally said that loud enough for them to hear him. This outburst made his face turn red of embarrassment as he tried to hide his face with his two hand puppets. Using Bunny to make it look like it asked the question. "It shouldn't hurt to add one more to the group right? Besides I can vouch for this kid dueling skills."
