I know he was being a smart aleck, but I had to pause for a moment reading Daredevil #8 when Daredevil greets the Black Cat with 'Finally, a woman I don't trust.'
He had good reason not to trust Felicia, since she was watching Spidey get electrocuted, but does that mean he trusted the Black Widow from the first time he met her? I mean, a former Soviet spy, who used to try and kill Iron Man? That is, when she wasn't suckering her previous sucker, er, boyfriend (Hawkeye) into doing it through an effective combination of playing on his affections and jabs at his pride.
Admittedly, that's part of why I like Hawkeye. He fought a guy who was basically a flying tank with a bow and trick arrows, and he did it for love (and out of his sense of bitterness at what he perceived as an unfair world). That doesn't change the fact 'Tasha was manipulating him for her own ends. Which is what spies do, and she is very good at being a spy, so maybe you can't fault her for following her nature.
It's hard for me to picture someone throwing over Hawkeye for Daredevil, but then I remember a) Hawkeye can be an unthinking clod sometimes, and b) Daredevil hadn't suffered through two decades of writers making his life an unending stream of misfortune and woe. Maybe that explains it. Also, lawyer. Wait, do I mean that as a positive (money, crusader for the oppressed), or the negative (lawyer = ethically dubious)? Eh, whichever.
Point is, things are finally looking up for ole' Matty, which is why getting involved with Felicia seems an odd choice. I get the idea dating a woman he already has trust issues with precludes him from being hurt when/if she betrays him/goes crazy/is murdered/commits suicide. Plus, she's a fun-loving woman with a devil-may-care attitude, which goes pretty well with Matt's renewed commitment to things like fun and an upbeat approach. But it still seems questionable just as he's getting his life together. Oh well, usually it's the ladies making the bad decision to date Matt Murdock. It's nice for Matt to take a turn making the bad choices.
