Data reveals Clendenning’s hidden knowledge

A volatile mix of puzzlement (surface) and dread (subtext). The puzzlement is genuine—she’s a scientist who prides herself on thoroughness, and the omission of Clendenning’s work from records is a professional affront. But beneath it lurks dread: if Data has Clendenning’s knowledge, what else does he have? Her son’s memories? The truth about the attack? Her smile is a shield, her silence a dam holding back a storm.

Picard witnesses Kallisko’s annihilation
