As we saw in the previous trailer, there was a lot of existential crisis going between Matt Murdock and Frank Castle. At the end of the trailer, we caught a glimpse at Electra making her first appearance in the series. In this trailer, we get to see the badass that she is slated for becoming.
Obviously, we see that there is great chemistry between the two and some animosity between Electra and Daredevil. The trailer, in this outing, focuses more on the action and impressive explosions. It is nice to see the secrets from the first season play themselves out in the coming season. March cannot get here fast enough.
