The alarm on Malak's (formerly Aishah's) watch wakes her at 5:30. This gives her time to get dressed, (Including a headscarf now that she has one again) sweep the room for mals, and build a little bit of mana before morning prayers at 5:45. Some of Aishah's crystals still have mana in them. She takes them with her - It's a bad idea to be spending down mana so early instead of building it up, but needs must. She puts up a weak nothing-to-see-here charm on herself - she'll need to do a stronger one later when she's actually doing something remarkable - and at 6:00 sharp opens her door and starts jogging across the school.
At 6:06 her heart is racing and she's standing outside of 255A.
