No, I'm not sure of anything. He could be off by himself / he could be off with ow. He could have rode with friends on a day trip. He could have rode to ow place and just be hanging out there all day. I can't imagine him going on a long ride with his hand wrapped up.
I don't know what he would be doing anymore.
He's been gone all day. I'm staying strong by keeping it in my mind that H is in his Alien fog right now. He is being a crazed teenager.
