Continuity mistake: In the food court scene, the first shot of Mariette shows her standing with two other replicants.

Answer: Think of any manufacturing process. Samples of new products are frequently created and then immediately destroyed. Also, the new replicant would require processing, training, etc. It was simpler for him to just dispose of the test.
