Dave, often called Grandpa Dave, was the elderly father of Jane Read, and the grandfather of Arthur Read, D.W. Read, and Kate Read. He first appeared in Christmas with the Reads, Part 1. Dave has Alzheimer's disease, which causes him to act very stupidly and forget everything.

Dave and Thora seemed to develop a completely arbitrary love connection even though they have nothing in common, other than they are both old. After speaking with Thora only twice, Dave proposed to her in Christmas with the Reads, Part 2.

Dave died on March 24, 2015, when he gruesomely removed his own heart to give to Thora Read (Waiting to Die, Part 2).
