Alvin's most common catchphrase
Alvin "Al" Marsh is the insane and abusive father of Beverly Marsh in the Novel It. Like Butch Bowers (Henry's dad) and Eddie Corcoran's stepfather Al occasionally abuses his daughter. Unlike Butch, Margeret and Richard he tends to beat and abuse Beverly for odd reasons, even though he doesn't smoke or drink (which are often the two key elements of Child abuse). While beating her, he constantly tends to say "Sometimes, I worry about you bevy, I worry a lot"
However, there are times when Al proves to be very loving and affectionate towards Beverly. He died from unknown causes in 1980. He also appeared as one of It's manifestations, taunting Beverly into getting out of Derry.
