So qbbh had his 0026 ticket when he first arrived, but just got a ticket with the numbers 0003, which likely means he's one of the originals, given that qbagi had a ticket w 0001 and carre w 0002.
If you're a frequent bbh watcher, you've likely experienced the random lore drops he gives. One of these lore drops was that he was stuck in a time loop, but got out of it, to which tallulah had said "what if your still in a time loop?".
What if he's still in the time loop, just like tallulah said, and this is his second time on the island? Could it be that the federation is able to keep track of ticket numbers, which is why instead of getting 2 tickets with the same number, he got two different tickets?
BETTER YET,
What if they realized he could be useful to them, and is an immortal demon, and then convinced him to join them (special guest theory maybe 👀), or need to do smth over (again) in hopes of getting something out of him.
⚠️ Putting my thoughts together: Maybe the first time he was on the island they noticed something useful, or learned info that they wanted to use, so they simply decided to restart, in hopes of taking the right path to lead qbbh wherever they need him. Maybe that's why they never punish him, they need something from qbad?⚠️
