Kanatas shocked face while seeing nothing but A WOMAN!11 OMGZ!
Good episode overall. On one hand its veeery convenient that theres another ship (that theyll use for spare parts). On the other hand if there wasnt a second ship, well, the story would be over. Or transform from "how do we get home" to "lets play civilization". ;o
As for the "whos the traitor" speculation, Id say theres only 3 candidates left: pink girl is the most suspicious with her weird behavior. Maybe we"ll see a SteinsGate, thoigh, and its the young girl. Ofc, the "out of nowhere"-twist would be Kanata. Maybe Theres more to how his teacher died and hes taking revenge of sorts.
