Do you think they will do something special for the upcoming 108th episode (which is the 4th episode of the season and premiers on the 23rd)? If so, what? Maybe it will be a numbers-centric episode. Maybe it will simply be very very very important and revelatory. Maybe they'll do nothing. Maybe they didn't even notice and are actually trying to tell a story at a pace that is unhindered by how many episodes they've already done. Either way, the fact that after Lighthouse airs they will have done 108 episodes will just be really cool for a week.
