Was Withnail expecting Monty's arrival?
So after Withnail chats to Monty in private at his house, we are obviously made aware later on (after Monty's inevitable arrival) of some of the outright lies Withnail has told about Marwood to secure the cottage. But was Withnail aware all along that Monty would be joining them or was Monty's arrival as unexpected as it was for Marwood? It could certainly be reasonable to assume, being the git he is, that Withnail was not only expecting Monty but relying on him, anticipating it knowing Monty would bring food and the finest wines available to humanity.
As Paul Mcgann says in of the documentary's, Withnail is willing even to trade his friends ass for a good time in the countryside.
What if everyone started telling the truth?
