So, Tim and Chris are clearly married, as is evidenced by their report-talk with Marcus.

Caitlin clearly fancies Tim, and is a very capable spy lady.

It's a shame Tim is oblivious to Caitlin's and Chris' flirting ways.

So, clearly, Chris and Caitlin need to meet, realise they both want Tim, and realise that in order to get Tim, they need to work together. And maybe strategise. And use ridiculous codenames.

And have a threeway.
