[ The first thing Kara does upon waking up in her room? Is zip to a corner and have a mild panic attack. The second thing she does it go to take a shower, trying to shake some of the feeling of... strangeness... off. There's no more hole in her chest and that seems almost wrong, considering the last thing she remembers was pain and light, right there.
The third thing she does, after getting dressed and such is read all the post-it notes from Steph with a small smile. Steph... Rao, she'd left so many people behind, hadn't she? That thought makes her flip through the journals, looking for Lois' handwriting and ignoring everything else until she finds that entry of hers. Kara can't help but smile shakily as she reads it. It was good to know that she was doing okay through all of this. Relatively speaking.
When she's done reading, she grabs a blank sticky note and just scribbles a few words on it before pressing the purple thing into the journal. ]
[ That done, she unlocks her door and moves to sit in her window seat as she just thinks and mulls things over in her head. There's so much to process, so much to catch up on. It's a little overwhelming, but she can do it. She's Supergirl, goddammit. ]
