Filming for OUaT began July 16. Lancelot (Sinqua Walls) will appear in the third episode, and a few others at the beginning of the season, which premieres September 30th. He may have to make a few more appearances, as OUaT is notorious for going back to characters the fans had previously thought were out of the show (ie. Belle, Jefferson/The Mad Hatter (YEEEEEEET!!!!! I love Jefferson. He knew what had happened even before magic and memory returned to Storybrooke...)). So he may have to do a few cameos, or something longer.

But OUaT should not interfere with Teen Wolf, seeing as season two is about to premiere and that the TW season 2 finale just aired.
