Answer
Cousin Del, portrayed by Crispin Glover, is a peculiar and enigmatic character in David Lynch's "Wild at Heart." He is Sailor Ripley's eccentric and unpredictable cousin, who often provides comic relief with his bizarre behavior and offbeat dialogue. Del's loyalty to Sailor is unwavering, despite his unconventional nature, and he plays a pivotal role in the film's surreal and dreamlike narrative.
