Occasionally, Matt truly did miss being able to see. Though his enhanced senses had compensated him for the loss of his sight in many ways, there were things that they simply could not replace. The inability to check his appearance in a mirror being one of them. He'd gotten quite good at coordinating his clothing, and he kept his hair simple enough so as not to worry, but he was allowed some measure of self-consciousness.
When he'd told Karen and Foggy about his encounter with the Russian woman at the coffee house, Foggy had not been surprised at all, chalking it up to the Murdock luck he'd come to recognize. Karen, though, Karen had seemed rather jealous...
But Matt decidedly wanted to know more about this woman. Something about her... was rather curious. Perhaps just his imagination, but after the crazy days he'd had lately, it was probably worth following up on.
And if it wasn't, then he got a nice dinner and a nice evening out of it. Fair enough trade.
