Jurati knows that they will let them go and she really wants to get to wherever it is Soji went with Picard.
It does not make her look innocent at all, as shown by the reactions of Raffi and Rios.
It makes me wonder where they are going with this though.
It seems like Jurati is going to have to "come clean" at this point that she's been working for Oh the whole time. Is she persuasive enough to convince Rios and Raffi? There's some scenes from the trailers of Rios and Jurati canoodling on the bridge, which suggests thing aren't going to sour just yet in terms of romance.
