Yes, Bill!

The Viyran walked around the half-nude colony for more than an hour, Bill's cheeks burning for all that time. She ducked inside whenever she could, breathless, before steeling herself and heading back outside again the moment before she thought it would be suspicious. She squealed each time, before schooling her expression. Thankfully the wandering Viyran didn't catch her.

Though plenty of other people did. Occasionally she got sympathetic looks from women just as exposed as she was, occasionally she got once-overs that made her want to hurriedly back away. Once or twice she got both from the same person.

Being naked was bad enough, but acting like it was normal... God, she never thought she'd miss using her hands for modesty, given that the alternative was baring everything.

Bizarrely the Viyran was a blessing; at least when she turned around and ran into it she had an excuse to squeal, pretending it was for reasons other than prolonged embarrassment. It stared at her until she hurried away.

Until, eventually, it moved towards where it had come from. The Doctor ran up to it.

"Seen enough?" the Doctor said.

I bloody hope so. Bill just about repressed the urge for snark, shivering.

"Study inconclusive," the Viyran said.

"Oh come on, it's more than that," the Doctor said. "No sign of the virus. Just normal everyday people. You've got nothing to do here."

It paused.

"Unusual readings detected," the Viyran said.

"Unusual?" the Doctor echoed. Now he seemed uncertain. "Unusual how?"

"Further analysis required aboard our ship," the Viyran said. "She will come."

"Who?" the Doctor said.

The Viyran raised one metal arm and pointed to Bill. Bill squeaked, eyes widening.

"No," the Doctor said. "You said it yourself, no solid evidence your virus is here, you can move on."

"Readings irregular," Viyran said. "She needs analysis."

"Try talking to a Viyran..." the Doctor muttered. He sighed. "And if she does, she'll be safe?"

"She will be unharmed," the Viyran said.

The Doctor hesitated. Then, quickly, he ran over to Bill; Bill squeaked, suppressing the urged to cover up again.

Damn it, she really didn't want the Doctor of all people seeing her like this.

"Doctor!" Bill squeaked. "You can't be serious!"

"They probably just detected that you're a time traveller," the Doctor said. "Me too, but I'm not displaying symptoms. It's like I thought; they can't directly view the virus so they're scanning for any abnormality they can. Once they realise it's just Artron energy you'll be fine, they'll bring you back. Won't take long, and while you're keeping them distracted I can work on a cure."

"I-" Bill said, biting her lip to stop from squealing again. She spoke in a stage-whisper, not wanting to be overheard. "I'm still naked! I can't go to an alien spaceship naked!"

The Doctor didn't say anything. After a moment Bill sighed, cheeks hot. Why couldn't she just have stayed in the TARDIS? That way none of this would ever have happened, she'd be content in the knowledge that the number of people who'd seen her naked were in the single digits, and under way better circumstances.

But, nope, instead she was walking around in nothing but her trainers, and meant to act happy about it.

Bill swallowed, and nodded.

"Fine," she said. "But next world we land on where the locals are running around naked, we leave."

Smiling slightly, the Doctor nodded. And trying to keep her back straight, the nude Bill walked over to the robotic-seeming Viyran, heading to the pod and giving the colony a last, long view of her ass.
