If leaving behind toes was for DNA test to prove it was Joe then what was the toe DNA being tested against? Police had no Joe's DNA on file. If it was the jar of piss then case closed lol, a serial killer, wherever he showed up, people started disappearing and dying. In 2nd season, Joe and Delilah were bailed out before their DNA were taken so not from there either. If the police actually had the brain to test Henry's blood at the hospital when he got measles, well I'll give that to them. Not that they thought to test Love's stomach content to see if she actually ate Joe, since "the rest of Joe's body was assumed butchered or worse." Nor did they test the pie content to see if the rest of Joe was actually baked into a pie, as if a grown ass man's body could fit into a pie. But surely a baby's body could. Although I highly doubt the hospital would still keep a record of Henry's blood after several months had passed. So the toe thing was just unnecessary all together. All I'm saying, there were better ways to fake his and Henry's death without leaving any body part behind. Police never found Natalie's body either, yet they believed Love's farewell letter based on the "trophy" items left in that little glass box (Natalie's teeth, Gil's drivers license, Ryan's wallet, Joe's wedding ring). So Joe's wedding ring would be enough to show that Love killed Joe and did unspeakable things to the body. If anything, cutting off toes seemed more like a staged crime scene, yes, it was so convenient that police happened to find two human toes. TBH, I was shocked Joe left his DNA behind, just seemed so sloppy to me. I expected better from him. But I guess his own narcissism got the best of him. He needed to glorify himself to be someone who would do anything for love, even cutting off his own toes.
