Spoilers Much!

I'm not planning to watch that episode of MacGyver until, at least, tomorrow.

Although I can confirm;

Director Thornton has most certainly been arrested. For treason.

And replaced by a much bigger character.

Also.

Are we sure it's a code?

So much as just being explicitly told something.

Repeatedly.
