I think a redditor nailed it again. Wayne knows enough of the parties involved to 'solve' the case but he's knuckled by Hoyt into an agreement for his silence.. but his dementia has lead him to forgot both how he's cracked the case and his agreement to stay silent.

Also, well ****ing played on feigning Harris James' internal bleeding / punctured lung act since it seemed like that's how he was going to die without rolling on Hoyt... instead of all but telegraphing shooting him.
