Needless to say, Data is not by any means unaware of the issues developing with the Captain; he had already had some inclination, based on the conversation they had some days ago, but that had been said in confidence. Of course, now things are reaching the point where he must share that information. Without Commander Riker or Doctor Crusher present, it does, after all, become Data's responsibility to see to the Captain's well-being.
His attention is grabbed immediately, of course - this matter of Seven experiencing issues is new information to him, one which adds yet another shade of emotional difficulty to that he has already been experiencing. His commanding officer, mentor and friend, and now his girlfriend. His own feelings aside, though, this is a serious point of concern for the wellbeing of everyone in the facility, and it is on that knowledge that he must act rather than these feelings.
"Do you believe you have been affected by the same issue, or that the Captain's difficulties are having an effect on you?"
