Clyde's thug and Warren are fighting! What do I do?

Not only are they fighting but they are constantly in your way.

The only place you can really access apart from the deck is the corridor.

Which leads to the kitchen, and the lift.

You'll find something you can use in the kitchen.

Get the saffron oil from one of the cupboards.

Make sure to discuss your plan with Warren by talking about the oil.

Now where to set your trap?

Go down the lift shaft and use the oil on the rungs. Problem solved.
