What I never understood about Nemesis was why, when B4 was discovered, they all acted so surprised that there was another android like Data. Did they all just have their memories wiped in regards to Lore?
I've never understood this complaint about B4. Lore is not an option, his remains are a known quantity. The crew know that there were more than just Data and Lore created, have discovered "unknown" Soong-type androids in the past...so their reaction seems pretty legit to me. Mild curiosity over having found another one, and Picard makes the comment about Soong having a penchant for whimsical names. What exactly is the problem?
