Back at Alpha HQ, they're looking at some of the evidence from the house. They're playing a Red Flag propaganda video narrated by a robotic voice, all about how awesome and how much better Alphas are than ordinary humans, with their narrow definitions of what is and isn't "abnormal." Cameron protests Rosen's shutting it off because he's the only one who hasn't seen it (and besides, he probably would like to hear more about how awesome he is), but gets overruled. Bill has found among the Red Flag stuff some plans for remote detonators and some information about an oil company called Northwell Petroleum. Looks like they're onto Red Flag's plan, sorta.
At the house, Nina blows off a curious cop while Gary tries to follow Anna's movements and seemingly random voice sounds. There seems to be a pattern, as she keeps going from the louvered closet door to a massager and brush on the dresser and back again. And when Gary turns on his phone, apparently that's the filter he needs to interpret what Anna's trying to tell him: "I can help you find them," she seems to be saying. Sounds like an offer Gary can't refuse.
It's night again, because I'm starting to see that Alphas occurs on an earth that not only has mutant superheroes but also rotates a lot faster than ours. Rosen's back at the house, and Gary explains that Anna's using her own language that only she can understand -- and Red Flag used her to encode their transmissions. Gary further informs Rosen that Anna understands every language, which Rosen tries out by busting out a little Swahili. Gary uses his EM powers to translate Anna's response to Rosen, "It's nice to meet you too." That's because she hasn't known him long.
Out in the kitchen, Rosen marvels to Nina about what this means: "She's a virtual Rosetta Stone." Everyone thought she was severely autistic, maybe even mentally disabled, but she just has a form of apraxia, an inability to speak. "No one noticed that she is an Alpha." Because that's a made-up thing, duh. Nina points out that Gary did...and so did Red Flag. Rosen's planning to use her to decrypt that computer tablet to help them find Kosar, but his triumphant mood is shattered when he gets a call from Gary's mom about the lateness of the hour. As you may recall, Gary's superpowers do not include staying up past 9:30.
