Without special equipment, Cybil wouldn't be able to pick up on what they were. She would find Timea's gaze was unfocused, although slowly improving. She also seemed to still have trouble staying awake, as her eyes were half closed, and her head drooped on occasion. There was nothing showing that any of this was related to the appearance of the spots, however.
She might also smell Timea's scent didn't match her appearance, having a more musky scent. She might also identify this as reptilian, although wouldn't be able to place what kind.
While hugging Hillary, Timea brought her free hand up to her forehead, rubbing it. After a moment, Timea shook her head, and looked over the room with some greater clarity, opening her mouth and producing a couple of muted throat noises, before finally asking; "... where?" Looking away, Timea realised that word didn't quite convey what she wanted to ask, but had trouble piecing together the right words.
