After the meeting ends, Xiulan stands and says to Jedao, “I’ll grab my stuff and meet you onboard.”

The speed with which she shows up with a bag slung over her shoulder says that said ‘stuff’ must have already been packed and ready to go before the meeting ever started.

[Pausing there just in case there’s any reason she’d have seen Remi between the base personnel rooms and the Cantata’s comms/gunnery room. Will post again shortly.]
