Imagine if they still hated each other like in the main timeline.
Henry would be trying to burn the pizzeria down every second he had while William would be trying to stop him every time like some bizarre Looney tunes skit.
Honestly, i always wanted to see a story where both William and Henry are killers and partners in crime, with a more healthy friendship than in the actual fnaf and they don't hurt eachother's childre. Both of them get springlocked and it would be funny if at some point they got their bodies fused
