The problem with
using one of the keys to commute home was that there was no way to control where the key brought you
back. Sure there was a chance that you'd end up in the same place that you'd originally left from, but there was also a chance that you'd end up two rooms over, on a different floor, trapped inside of Principal Connor's filing cabinet, face to face with the enraged leftovers of Wednesday's Meatloaf Surprise, or worse.
In Angelus's case it dropped him off by the indoor pool.
Specifically twenty feet
above the indoor pool.
Angelus could be heard to say "Oh
sh-" before there was a loud splash.
Fortunately not needing to breathe removed one problem from the equation of trying to right himself, get oriented, deal with the tangle that his clothes had suddenly become, and then get to the edge of the pool. He pulled himself out, carefully cradling a package that had originally been safe inside of a grocery bag, but the paper bag had turned into a sodden mess.
He bundled the bag and its inventory into a makeshift sling made from his coat, then squished his way back to the fourth floor.
