It's definitely a start, and John is perhaps a little bit proud that Sherlock seems to think as much. Proud overall, really, because it's one thing to learn a wand motion and perfect it and an entirely else to only have words and an idea for what they want it to do, and do what you can from that.

A lot of satisfaction, and John smiles widely at it because, well, why not? "It's still only morning," he says idly, and repeats it.

The cup still doesn't manage to stay up, but it takes a little longer to fall this time.
