Re: Kidnapping
Sirius watched everything from the shadow of a nearby building. He'd given Remus the slip a few moments before and was enjoying this little domestic squabble immensly. The mudblood and the blood traitor were putting up a good fight, but he was surprised to see Snape coming to the little sluts aid. He knew the Slytherin was hot for her, but was that a reason to turn on your principles? Sirius didn't think so.
He ran out of hiding and over to James, flashing him a disarming grin before firing off a full body bind on his so-called friend and wrenching the mudblood out his arms, propelling her toward her attackers and away from Snape and the now prone James.
