Spoilers/Easter Egg in Deep Breath

Hello Sweeties, Doctor Song at the moment and just pointing out a Spoiler or an Easter Egg in Deep Breath.

In Deep Breath, the first episode of Season 8 with Peter Capaldi, I saw this... Capaldi wears a skin mask to blend in with the clockwork people and save Clara. If you slow the episode down, you can see Capaldi turn like the way Smith used to when he was the Doctor. If you pause it at the right moment, you can see that the skin mask looks identical to Smith's face. I just thought this was a cool little regeneration easter egg Moffat included. Bad Wolf actually pointed it out when she came over to see this one night. Thanks for reading this guys! Hope you were entertained! (I bet now most of you will go and watch the episode again to see if I'm right)
