I was thinking more along the lines of her in the blonde wig and low-cut dress at the event where they confronted Jarvis, but I haven't found any images online that really bolster my claim. The first couple of replies in this thread at least indicate I was not alone in thinking so.

how is it they left layla inside the protective bubble but the doctor was out for the interrogation?

The Dr. is an alien and they are immune to the virus.

I just finished this up last night and I'm crossing my fingers that it doesn't end on some major WTF? cliffhanger. Not holding my breathe.

Ian Anthony Dale said on Twitter that there is no news yet on a possible pickup elsewhere.

i understand she is immune. but opening up the protective thing seemed stupid since they didn't know what was going on.

No point in nickpicking at this point, or we'd also point out that immunity to something doesn't mean you can't be a carrier of it (and thus infect people who aren't immune). Just go with it for one more episode and try not to think too hard.
