Magnus is so good at not making a face when people mention Susan. He's like a Susan non-reaction expert these days.

"A stereo is something they can play the radio on. It's big, it's loud... anyway, it was right before Christmas, and they wouldn't stop freaking playing the Christmas songs radio station -- that's, like, every radio station in Boston in December, by the way -- and long story short, I broke the stereo. Like, completely destroyed it."

It's possible they would have let him back in eventually, but he never got the chance to find out... after all, he'd died three weeks later.
