If they're not going to tell her, fine. She'll look at what she knows.
Lalita, who is even stronger than she is, remarked that the cabinet was heavy - Dr. Hall didn't use any obvious trick to activate some technology attached to the cabinet to make it easier to move - he moved it anyway - Lalita noticed - he attacked.
Dr. Hall is undercover as an augment, or possibly some kind of human-passing alien. The possibility of being noticed is sufficiently distressing that he's willing to blow his cover for a better chance of escaping instead of hoping he was overreacting to Lalita's facial expressions. Or, no - he attacked Lalita before even seeing his face - psi, maybe, or just putting together the fact that the cabinet had been moved in the first place. This instead of - taking her hostage, or perhaps re-injuring her to the point where she'd be unable to summon nurses or other doctors herself and hoping to convince Lalita to remain behind while he fled. Which might suggest any number of things but probably rules out sheer malicious madness of the kind the opponents of genetic engineering expect from augments as a rule. He was working as a highly competent doctor, for crying out loud...
And eventually, they just... stop.
Dr. Hall has Lalita pinned to a wall by his shoulders—Lalita shoves him away—he recovers his balance and then, instead of attacking again, shrugs slightly and takes another step back.
"Well that was interesting," Lalita remarks. He glances at Isabella and adds, "Sorry I didn't answer you before. Too busy."
"Yes, I figured that out. Is attempting to confirm what else I think I've figured out going to get me killed or held hostage, or have you sufficiently - communicated with each other?"
"Augment. Mostly human. Some Vulcan, some Betazoid, and that's just what I've identified; there could be more I don't know about."
"So, a little psi, enough that you didn't have to spot Lalita ruminating before reacting, but not enough to catch on before now, or enough to figure out without assaulting my husband that we are unlikely to turn you in."
"I don't get thoughts, just feelings. And I have enemies. He could've been one of them. He isn't, but he could've been."
"Enemies who'd plausibly turn up as the spouse of a phasered political activist."
"Not looking for me. They don't know where I am. But there's nothing stopping someone who just happens to be with them from showing up here on other business."
Since he seems so talkative now.
"I'd call it May-December but he's liable to outlive me, assuming no generally applicable immortality is invented in time. I found out when he accidentally hacked into some of my files and then didn't think to cover his tracks."
"And one of the things he found was a half-finished pseudonymous essay which contained my opinions on augmentation. In addition to enough information to tell him what the Prometheus was up to between surveys, if you've been paying attention to exactly what kind of political activist you had for a patient." She pauses, then says, "T'hy'la - come here a moment?" And she lifts one hand, by the elbow, not the shoulder.
So that she can get out of this damn bed.
He holds Isabella's hand, so he can get his face back without breaking contact, and turns to Dr. Hall.
"So, among my other interesting properties, anyone of a compatible species who gets a blood transfusion from me has massively accelerated healing for a little while. Isabella's a compatible species. I couldn't manage to sneak her off in time when she got shot, and there wasn't as much point since you fixed her, but now we don't have much to hide from you and she'd like to maybe get out of bed. Could you cover for a sudden miraculous recovery?"
