The Character Reveal Teaser #2 was released on the Rooster Teeth website on August 3, 2018. It can be found here.
Doc: That's enough Chase. Return to base.
Marin: Dr. Weller.
Doc: Colonel, you'll be pleased to know the refinements to the endoskeletons are performing nicely.
Marin: Why have I received a transfer request from the Mesa?
Doc: How are things with the war effort? Hard to find anything positive in the headlines these days.
Marin: The Vanguard's been reduced to strictly running defense, all we're doing is slowing them down. I hope your progress report is better.
Doc: Indeed, I have fantastic news! I'm about to "double" the number of pilots in the program!
Marin: You only have one pilot so far, doctor!
Doc: How did I know you'd see this as glass-half-empty? But I think you'll like this candidate. Yasamin Madrani. Just like Chase, She also has a significant military experience, top of her class in infantry training, flew as a combat pilot... Just "one" little thing.
Marin: No... Por favor!
Doc: You have to release her into my custody.
Marin: From the Mesa?
Marin: The Mesa Detainment Center.
Doc: I need you to keep an open mind here!
The call terminates.
Doc: Can I take that as you'll think about it?
The images are followed with the name of the show and an expected January 2019 release.
