When Thomas gave a respectable bow to the King of Dragons, he just looked towards Thomas and gave a very small nod, then returned to looking forward into space once again. Then Ascot approached Bahamut, the dragon turned humanoid looking towards the boy as he began to talk about the two of them being friends. He didn't say anything in response, but instead gave him that very same small nod that he gave to Thomas before looking back forward into space once again. He didn't really speak much, if at all really, but according to Oner he did indeed talk to him and his other self. 

When Ralph approached though Reno manifested in the blink of an eye, replacing Oner, looking up towards Ralph and gave a nod when he said that they should let Vanellope finish the race. "Yea that sounds like a fun idea. Maybe me and her can have that rematch~" He grinned as the kart he had made at that kart factory materialized out of thin air next to him with a snap of his fingers. 

As for the other question, Oner manifested to answer this one. "I don't believe we did, do you have any idea where it could be?"
