"Yes, I'm here - Regulus said you'd managed to find your way down here." He raised an eyebrow at James when he told him some about his night. "Snape loves you and gave you lots of whiskey?" He wasn't going to get used to hearing things like this about Snape. "It sounds like you have had an interesting night, you want to come home with me?" He asked James an amused grin on his face.
