So, my brother came home a while ago and I had him watch the trailer in an effort to translate. He didn't have the time to give a full translation, but here are the Cliff's Notes of what goes on: The opening is an ad for Terra Save. In it, they talk about all the corruption in the people in power and how you can TRUST Terra Save, who are fighting bio-terrorism worldwide.
When we see Claire, most of what is said are normal pleasantries. Moira salutes 'Claire-senpai' and swears a bit. Claire tells her that they're close enough to drop the formalities, then the bearded guy (Neil) pulls Claire aside to ask if she has heard anything on this new, horrible virus. He asks who the other girl is and Claire says she's the daughter of BSAA's Barry Burton. Neil says she takes a lot after him. He also talks about how she doesn't have high enough clearance to be privy to the information he and Claire are discussing, and says they can discuss it at greater length later on.
When they check back in with Moira, she is trying (and failing) to get a hold of Barry and says something along the lines of "He's always at the beck and call of the ****ing BSAA, but when I need to get a hold of him..." before all hell breaks loose. We couldn't quite make out what the terrorist says to Claire.
And that's basically all he had to say. He told me that, if he can find the time, he'll attempt to go more in depth.
