Bix drugged Cassian to enable her surprise departure
“I’m done, Bix.” Cassian says.
“Have your tea,” she responds, sliding a cup towards Cassian.
It’s always bothered me just a little that Bix leaves during the night and records a message without waking Cassian (who we would think may be somewhat of a light sleeper, always ready for action).
Cassian sleeps through the night (he seems a little surprised by this), and Bix clearly was planning this before he got back from Coruscant. If he wakes up while she’s leaving, he definitely resists and Bix may think she doesn’t have the strength to get through that argument. So she resorts to (lightly) drugging Cassian.
Maybe relevant, maybe not: Bix used drugs in the 3 BBY arc. Perhaps she knew the perfect dosage to keep Cassian asleep through the night without any risk of other damage?
Just a little something I noticed on my 8th (?) rewatch.
Also I appreciate Diego Luna’s nonverbal acting more every time I watch.
