Jericho says his name?

The kids were outside sledding on the last bit of snow. It really is nice out. They disappeared around the side of the hill and I didn't know where they were. When I called out to them, Gabriel reappeared first and said that they made a friend. He also said that Jericho said his name. I've never once heard Jericho say his name. Many people have asked him, and he always sits there in stony silence. So I didn't personally hear him, but I guess I'm inclined to believe Gabriel. I just wish I could have heard what it sounded like. Maybe I'll hear it some time in the future when someone else asks him his name.
