[As the last notes quietly come to a close, so should the effects have taken hold... no matter how powerful Saya, or Diva, is. When she manages to try and lunge though, Tear can't help but start forward herself-- to shove the girl to the side, to raise some small shield, to keep Diva from tearing Hei apart in the moment before she's out-- but pulls back short once it's clearly unnecessary.
She studies Saya carefully to be sure that she's completely under while taking another, hesitant, step back to keep her space, before flicking her eyes over to Hei; her own "mask" up now, voice indifferent like nothing at all had happened here]
If you don't rouse her, she'll be out til morning. [And hopefully by then... back to herself]
[Also, that'd be his cue to get out. When it's convenient for him, of course]
