Up: Micro and Castle

Fans may be displeased by liberties taken by Marvel and Netflix when they brought some of the show’s characters to life. For example, this is the first time we’ve heard that Russo served in the military with Castle. But we can’t deny that this show’s version of Micro is perfect.

One reason for this is that the relationship between Micro and Castle evolves over the course of the first season. Interviews with cast members indicated that the characters weren't going to see eye-to-eye at their first meeting. This is a common trope in this genre, but it isn't too obvious, thanks to the way the characters are constructed. Their relationship evolves organically from one episode to another, and Micro and Castle realize that they need each other.

We don't know whether Castle will find a significant other in the future (Deborah Ann Woll revealed that talks have taken place). He may not, but Micro and his family could give him a reason to continue.
