"Mmph" Willis frowned as he could only wonder what the lad wanted, he seemed nice enough but Willis knew all too well that appearances could be deceiving and he could do a number of nasty things which could be seen as "Fantastic ideas". Then again what motive did he have against Liz or himself for that matter? As far as Willis could tell they had not done anything wrong and the lad didn't seem Neurotic enough to plot against a person for something trivial. Perhaps he had been stalking them for several months and he was in fact a hitman? Or maybe he was going to enact revenge because Willis had dishonoured his grandfathers, uncles best friend. 

But no, Willis knew he was probably just getting carried away again and so he put the thoughts out of his mind and done his best to smile after such a long frown.
