Jacob puffed a bit as he finally caught up to Olivia. Those stairs put a bit of a stitch in his side. He spent most of his time reading, not running. Yikes. He had seen most of the scene unfold as he was making his way up, the hair yanking and the spell casting and whatnot. The fat friar -- a ghost Jacob actually thought seemed pretty cool, not like the terrifying, super scary Bloody Baron -- was floating around, and there were a couple of Gryffindors he didn't know up there, too.
