Elektra’s appearance was the cliffhanger in Penny and Dime "“ breaking into Matt's house to request his help with some legal issues (oh, the irony). Obviously, that wasn't the reason why she came back, but hey, does it really matter at this point?

Elodie Yung's Elektra is the perfect combination between sexiness, playfulness, and lethalness. And this is better revealed in a flashback scene (the episode is riddled with them, providing the necessary backstory), when she takes Matt to the house of the man who killed his father. Quite frankly, that flashback is the best scene with this character, since it perfectly captures her excitement when it comes to killing.

And this once again shows that Matt isn't going to break his no-killing rule, even if he is (in some way and to some degree) in the same position as Frank Castle.

Her intentions are slowly revealed, since she wanted from the beginning to attract Daredevil (she knows Matt's secret identity) into a fight with the Yakuza (she also knows that the Yakuza is actually the Hand). Unfortunately, or at least to our disappointment, the cliffhanger of the episode is not what we expected "“ a fight with the ninjas. Instead, it just shows them all prepped up for the fight.

The relationship between Karen and Matt is also moving forward, and they try to go out on a date. It doesn't work out at the fancy restaurant, since Matt believes that cheaper is always better. And this goes to show that he is in no way like the bigger superheroes of the MCU "“ he is just a guy, trying to make a living while also protecting his neighborhood.

Karen can now be considered a full-fledged detective, since she digs even deeper into the past life of the Punisher, with whom she actually agrees (or, at least, she isn't certain that Frank should be blamed for his actions). She also comes to suspect that there is a cover-up in progress as far as the Punisher killings are concerned "“ yes, some characters were too obvious in their actions.

Also, some references are made to the larger shared universe. But they don't overdo it. Which is, yet again, very nice. We believe that, as much as possible, these storylines should be self-contained. And it isn't just because a series (or movie) should be understood only by watching it alone. But also because, in this way, the material doesn't become too dense and overcrowded (yes, even the absence of characters who are just mentioned can be a form of overcrowding).
