John looked up at Sherlock with a little frown. "Sherlock. Be nice." He scolded lightly, though he did actually look stern. "She can ride with us if she wants to."
He wasn't quite sure if he actually just didn't like this girl - she seemed perfectly nice to him, so he didn't really know why - or if Sherlock just wanted to spend time with John. Which he was sure they could do plenty of when they were in the castle. He smiled up at her, holding a hand out. "i'm John Watson. It's nice to meet you." He said cheerfully, looking curious, really. He'd love to learn more about the friends... well, Sherlock had said he didn't have any friends. Well, except John now, apparently. But the people he'd been around since he was young. Perhaps he could get some embarrassing stories, too, which was a nice thought, and good bribing material. John would love to have something to tease Sherlock over - just friendly, of course, not meanly.

(alright, that sounds good! :D
That's fine, don't worry about it. x3)
