S1 E5 SPOILER ALERT
So can someone please explain me some details of this episode.
I understand Li Than (in the cast list only "VC peasant women", I don't know why they don't mention there the name she has in the movie) is the traitresse; she's the one who gave the informations to the buddhistic monks. Tran found it out and ... ???
1) What did Tran do in the weapons stash when Taylor, Johnson and Percell were watching him there?
2) How did Li Than kill Tran?
3) How did Goldman etc. find out that it was Li Than who had killed Tran?
English is not my first language. Any corrections are welcome.
