Intriguing question.

If he was preparing to set off a bomb, like Doug, I don't think it would make all that much difference whether you sat next to him or not. On the other hand, not sitting next to him would imply that the animals who set off the bombs in London had won and created a division where none previously existed.

I think the safest option would be to sit next to him and quietly inform him that you carried a device linked to your heartbeat and cunningly disguised as a wristwatch which, if disrupted, would send a signal to the UK's Nuclear Arsenal with an instruction to prime and launch an intercontinental ballistic missile towards Mecca. That should cool his itchy fingers.
