Excellent! I was reading Sirius and Ginny - loved it! I can imagine Jamesie would be rather awkward for Ginny to bump into, and with James being the known red-head lover he is, it could become even more awkward, lol.
And James is always on the lookout for those who might see through his pranks - if he could prank a prankster, it would mean that he had excelled above and beyond his greatest expectations. Then again, I'm pretty sure they will get along like a house on fire :)
