Portrait of a Character – Josh Rosen

Portrait of a Character – Josh Rosen

Josh Rosen was originally an afterthought – sorry!


First seen in The Light, Josh starts off as something of a background character in my Star Trek fanfiction. Friends with Ethan Shapiro, Karin Bernstein, and Andrew Miller, Josh was originally just meant to be more expositive filler material and not much more than that. Along the way, I found other ways to make him shine.


Josh is played by Seth Green.

Portrait of a Character – Josh Rosen

Seth Green as Josh Rosen

I like how this actor can be rather affable in some portrayals whereas, in others, he can be utterly menacing and evil.

I also like that he plays nerdy rather well. Josh in the prime universe is an engineer, and that is often my experience of engineers. Since he is a security guy in the Mirror Universe, that also works with the actor.


Dutiful and loyal to a fault, Josh is almost like Malcolm in that he will do nearly anything for the people he works for.

In the prime universe and prime timeline, he is pleasant and funny. In the E2 stories, he is a romantic guy but also is truly perplexed as to how to fix the problems that his marriage has created, and the wedge it has forced between him and his friend, Ethan. And in the Mirror Universe, in both the Temper first alternate timeline and in the prime timeline, he shows a loyalty and devotion to his mother that no other Mirror Universe denizen shows except, perhaps, for Doug Beckett.


Karin Bernstein

Josh’s relationship with Karin only happens in the E2 stories, although they marry in both iterations. He is playful with her, calling her angel and generally surprised that she would go out with him, let alone marry him. In the second kick back in time, Karin herself wonders a bit about why she didn’t pursue Andrew herself. But the answer is the same for both iterations – Josh gets there first.


In the Mirror Universe, the start of this relationship shows up in He Stays a Stranger. Josh has fairly recently struck out with Leah Benson (although he did help her to escape the Empress), and he is alone. When Daniels and Tom Grant  get the Flux Capacitor back, Josh ends up on Lafa II. Telling her that he doesn’t know anyone, she tells him, “You know me.” When Branch Borodin, a millennium later, explains that time period’s events to a tour group at the Temporal Museum on Lafa II, he mentions that Josh became High Priestess Yimar’s consort.

Mirror Universe

In the mirror, Josh Rosen is a security crewman, and often guards the Agony Booth.

But he wants to get out. He also well aware – more than most Mirror Universe denizens – that he needs to help others so that they will help him.

Hence in Temper and The Conspiracy, he is a part of the plot to get Chip, Lucy, and Chip’s two children off the Defiant.

Once they are gone, he still wants to get away, but he’s realistic about his chances. In Bread, he helps Leah Benson leave, as a fulfillment of his mother’s dying wish.

His continued caring for what his mother would have thought of him marks him as one of the few righteous persons in the Mirror Universe. This puts him on a par with Doug Beckett.


“We’re members of the same tribe. There aren’t a lot of us left. My, heh, my mother sent me a last message last week, before she died. She said I should look out for anybody in the tribe.”


This below decks character shows up a lot. And he has been a bit of a utility infielder character, ending up in nearly every series but Hold Your Dominion and Mixing it Up. Not bad for the guy who, at the end of The Light, is neither the star (Ethan) nor the romantic lead (Andrew).
