With all that blood she had everywhere else, Mauve had one long drip of blood on the back of her neck- just one.

So they make it all the way to the lake and no one thought of washing off the blood on their face? Strange.

I was thinking when (mild S2E6 spoiler ahead) Bernard had blood on his face maybe they were doing it to differentiate the various characters/timelines? Like marking the Stormtrooper helmet of Finn so we can pick him out in a crowd, only in this case it would be picking out one Maeve/Benard/whoever timeline vs another.

All that being said, Bernard had a clear blood pattern in Ep 6, but then goes back to a clean face. And the time jumps and in-program/out-program experiences are completely disorienting.

That works for Bernard since there are time jumps and in-program/out-program experiences and we now know there have been many Bernards but,

Maeve was in Shogun world with Japanese people and dressed like a geisha- that differentiated her from her other timelimes, so they could have washed off the blood- which she did anyways when she changed clothes.
