The tenant in room 7 is very small, very twisted and very mad.
A young man carrying a big basket that contains his extremely deformed Siamese-twin brother seeks vengeance on the doctors who separated them against their will.
Duane is described as being "about 20 years old", making his birth year ~1962. The flashback is set 8 years before Basket Case, when Duane and Belial were 12 years old, as it is stated before the separation surgery that "I've had 12 years of doctors' second thoughts.".
