The Purple carrier and the heavy bomber dipped below the cloud line in the battle after being damaged. It seems that they didn't explode, so they managed to get away. Though they may have warped into another pocket dimension where Yamato will end up in the film when it runs from the Cometines. The blonde guy was one of Burger's pilots, so three of the foru Gamilas shown were survivors from the Rainbow Star Cluster battle. The woman seems to be in command of a fleet that has a few battlecarriers, a type we saw only one of during the first series run. Even during the massive fleet review, we didn't see any of this type with the other fleets. As for the new look for the Cometines, I think that will be interesting. They do look like a cross between TOS and TNG Klingons, just with green skin. Sabera looks nice as well. She'll be a problem later on if the series continues.
