Sunday's latest 'Walking Dead' installment, "Inmates," capped off with the long-awaited arrival of comic characters (though they weren't named in the episode) Abraham Ford, Rosita Espinosa and Eugene Porter. This coming weekend's all-new episode, "Claimed," will shed a bit of light on the three major arrivals, as well as their mission, and we've got an exclusive first look at 'Twilight' star Christian Serratos' lovely Rosita in action!

Consider yourself warned of spoilers for 'The Walking Dead' season 4 to date and potentially the comics, as well, though it's safe to say Glenn may not like what he finds after he comes to, having passed out just before Abraham, Rosita and Eugene showed up in a military truck. The comic trio held an important life-and-death mission to follow in Robert Kirkman's original books, while poor Glenn just wants to reunite with his beloved Maggie, wherever she may be.

It's hard to say what exactly 'Twilight' star Christian Serratos is thinking about in our exclusive image from Sunday's "Claimed," but either way dual sidearms and some serious shade remain at the ready. Meanwhile, here's what AMC had to say about Sunday's new episode:

Just when Rick thinks he's going to be able to relax, he's faced with multiple immediate threats. Other members of the group deal with their past.

Hard to say if Abraham, Rosita and Eugene could be considered "members of the group" just yet, but what do you think? Will we learn what they want from Glenn and Tara (Alanna Masterson) by this Sunday? What unique relationship might Rosita have to either Abraham (Michael Cudlitz) or the enigmatic Eugene (Josh McDermitt) in AMC's adaptation?

Check out Christian Serratos as the lovely Rosita Espinosa in our exclusive first official look at the character from Sunday's installment, and tell us in the comments what you want to see "Claimed" by the latest episode of AMC's 'The Walking Dead'!
