He obviously has no problem with staying which would be why it hasn't come out, maybe he wants to leave but understands its almost no chance of happening. Gibbs the 2nd time around was pretty quiet until the deal was almost done.If he wanted out and I don’t know how it’s been kept quiet for so long it would have to be 8 and future if he was OOC. Given his in contract I’d be wanting more.
FWIW I thinks there’s a reasonable chance Oliver had an issue. In fact I’ve heard that off people but not sure of the legitimacy of it. However issues weren’t at a level of him leaving necessarily.
