Vincent had a lot to do when they headed back to San Diego. He had to wrap up the loose ends of his life and get an alibi in place.
He needed to finish the first of his humanlike robots—the ones that looked like him and Maya. She hadn't been in the garage since she finished her work and didn't realize he had started on a second one or was nearly done.
These ones were a bit rushed since he hadn't had time to properly create fake skin that could be replaced once the weapons' systems were retracted. If they ever had to use them (which he doubted), it would be obvious they were robots but there was nothing he could do about that now.
The robots he used for his infiltration missions had to be much cleaner. These were only so he could get out of here without anyone realizing he had left.
