It's not two lynches into LyLo, because the Indie has no reason to side with Mafia given that they need them dead too. In the worst case, Town mislynch twice, the hider dies, Mafia successfully kill twice and the indie kills once, that leaves 12 going into Day 3. 5 Mafia votes, 1 Serial, 1 Neutral, 6 town. And the indie serial has to town side here. You're conflating losing majority outright with LyLo, and I've already explained this to you earlier in the dead chat, so I have no idea why you're back repeating the same argument.
Town will always get 3 mislynches to work with, but even if they mislynch in the above scenario, which would rely on the Hider not using their role even close to correctly, they still have 4 players worst case going into Day 4, vs 4 mafia (5 votes) and 2 indies. At this point, it depends on the neutral indie. If they were recruited by the serial they townside. If they're purely neutral, they can stall, but have no real incentive to do so as it means the serial can just recruit them. They could lynch the serial with the Mafia, but it needs the Vig, jailer and the duelist all dead to bank on that. So in most scenarios (not all), town should still have 4 mislynches.
What you are doing is presenting a scenario that cannot actually happen but theoretically does from a numbers perspective, and then conflating LyLo with voting majority.
