Alas, Tabby's movements are invisible to her. There are no ripples that make it up to the surface of the water. She's resting again, listening to the emptiness of the huge room around her, but there's no splashing to make it up to an echo. She's too drained to even bother being conscious with kenning, and her eyes are closed.

So really, she's only got a weird nagging feeling to go on. It feels like she's being watched. That isn't exactly weird to her anymore, but it still gets her to crack her eyes open, glance around, and push herself up a little.
