I'll go ahead and punch in the time-card for Mr. Enclave too. Wouldn't want him to be late.
Thanks compatriot, we have to go through the motions it seems.
James killed himself in a hasty and foolish attempt to destroy his purifier, end-of; even if he had wanted to sabotage the Purifier, he could probably done so and had a more reasonable chance of escape had he just gone along with Autumn. And even then there's zero indication that Autumn would have betrayed him given Autumn's later revelations and motivations; James, as the project leader, would have been a very useful asset to the Autumn regime.
EDIT: And Nielsen, stop collecting pay-checks and make some good movies.
