I like to imagine he's an ironically good, but creepy boss.

Like one that'd give you 8 months of maternity leave, but would constantly have very ambiguous speech about eating your kids. Where, after some weeks you might think "Oh, maybe he's just misunderstood" -and then you just see him eat rats in an alleyway.

Or the guy that sexually harassed the new intern "disappears" and Mr.Gibbs has a suspicious bloody mouth and flesh bits hanging from his teeth and suit. On the same day, he invited that employee into his office "to talk"
