A military bigwig arrives to inspect the training facility, and to also tell the two dozen or so candidates that only six of them will make the cosmonaut cut. When one of those candidates screws up their parachuting drill, Lev is suddenly back on the active roster. He might end up in space after all.
Meanwhile, Irina is in the anechoic chamber, which she basically treats like her coffin, only larger and most likely quieter. While in there, she’s left alone with her awful memories of when her village was massacred and her parents torched. At one point she softly calls Lev’s name, and can’t help but grab his sleeve when he finally comes in to release her from her solitude.
Irina probably figures she can’t hide the fact that she doesn’t hate Lev’s guts, so she comes right out and says she considers him the only human who isn’t bad. I’m not sure what that pink-haired researcher did to her! All joking aside, we get another great skydiving scene with Irina ending up in the unenviable situation of having to stare at Lev to keep her head up, even if it means being unable to hide her blushing.
When the two are up in the air they can forget about all the awfulness that surrounds them, but they come back down to earth literally and figuratively when they witness an aborted space capsule flight and the corpse of one of the experiment dogs. Those horrible flashbacks come roaring back, putting Irina in a state of shock.
Lev’s superior picks them up, and tells him that no one was supposed to see that. Back in the command room, the mission commander battles both his ailing heart and the political reality of having to self-destruct Irina’s capsule should she land in another country. You can tell he’s way more in this for the science and discovery, not the patriotism.
