Though approaching the scene might have looked a little odd at first glance when you had Sebastian Sullivan in his best coat talking with a feminine figure. He was relaxed though and just looking as though she had said something particularly funny. The girl reached out though to straighten his scarf before he kissed her on the cheek and ushered her off. A little power borrowing never really harmed anyone now, did it? He considered before turning back to trying and keep an eye out for Penny. Bast wasn't even sure what he would want his sister's power for, but it was better to know these things then not know what he was doing. Worst came to worst, he could hide Brendan's dirty laundry for a hour or so.
He smiled faintly when he saw Penny though and just waited for her to get over there rather than fight the stream of students. "Here I thought you might be a little bit longer. Can I carry that for you?" He offered, motioning to her bag. It would save her the trouble of needing to carry it and make it a little easier to walk across all the snow.
