Hussar

Typical "don't know who you can trust" scenario.
Well, here is my prediction. The good doctor is actually dead. In her place, the Romulan agent (whose name I forget) has now inserted herself into the group. My reasoning is this:
1. Where did the doctor come from so conveniently? And how did she shoot from outside with a Romulan disruptor?
2. Why were the Romulan assassins so bad at their job?
3. We already know that Romulans can be altered pretty quickly.
So, sometime later in the season, it will be gasp revealed that she is a Romulan spy! Of course, Picard will already have figured this all out and will have some cunning plan in place to catch her in the reveal.
