It's at the very end of Verse 1; in the Japanese dub, there's that echo-y affect on his voice (meaning that it's a thought) when he says "How can this be? Can she really see my moves?" then Sara says, out loud: "It's not my eyes that see them," which reinforces what she said about being able to see people's aura.
In the English dub, he says that first line out loud. Not a huge deal, but when I watched it in English first and then noticed the difference, I thought it was much more awesome to suggest that Sara can read minds on top of slice through stone/stop the rain.
Spoilers
When I watch this show, I always imagine Jin and Mugen to be unbeatable (which in essence, they are, considering how in every episode up until now they've been slaughtering everyone), but seeing Jin losing to the blind girl was something else.
End
Just wait. Arguably no one up until now, or afte, has been a bigger threat for them.
