I actually wanted to write my own take on the epilogue.
During the tau part, Xeno was actually fully awake, and getting pissed every time one of them called her an 'it'. When they call her feminine and statuesque, she's thinking: "Oh, so you finally notice I'm a woman?"
Immediately after the dialogue she's so tired of their bullshit that she simply decides to go back to the Vessel Formerly Known As The Su't'ji and gets up. The tau are shitting bricks, which she thinks is hilarious (but she doesn't show). She casually walks to another section of the lab where drone excitedly crashes through the wall. Xeno congratulates her daughter, telling her how proud she is.
SECURITY TAU ARRIVE! PEW PEW PEW!
Their shots bounce off and don't even tickle. Xeno and drone go to next section where Weaver's cocoon is being held. Drone loads it on her back, and they go on their merry way. Security tau keep shooting. Security tau finally give up. Young earth caste woman asks about her cute braid.
