Con-Strained unfortunately actaully was once constrained in a cave with Con-Taminated, it is also there that he lost the extra arm that nurgle and nuffle had granted him. That stupid chainsaw wielding fool.

Interestingly Con-Strained is the only memeber of the team to get close enough to Con-Taminated to see the nurgle rot, interestingly when he first saw him he said there was no nurgle rot, although as soon as the chainsaw broke Con-Strained's Skin, somehow the rot appeared from no-where. (i'll leave that very simple puzzle to you)
