Character Profile: Lore

He's back! ...maybe? Definitely. Er, we think, based on a few seconds in a trailer!

Brent Spiner (possibly!) returns as Lore in season three of "Star Trek: Picard." The trio examines Lore and his relations with the Next Gen crew - how evil is this evil twin? He only appeared in three (or four, depending on how one counts) episodes: "Datalore," "Brothers," and "Descent" (Parts 1 and 2). What makes Lore the antithesis of Data? What is his motivation? What more did we learn about Data and his "family"? Let us know all the lore about Lore!
