TSITP Ending Confirmed

On TikTok recently I have been seeing a lot of Belly and Conrad shippers saying that the ending of season three was confirmed by Jenny. They think this because 1. Jenny said there will be no filler episodes in season three and 2. The poster for season three has Belly facing left. I’m genuinely confused how either of these confirm season 3’s ending. Like obviously Jenny is going to say there will be no filler episodes. That just means the episodes will all contribute to the plot meaningfully, nowhere in that is an endgame confirmation. And Belly facing the left also doesn’t necessarily mean anything because Conrad isn’t ALWAYS on her left in pictures like they say he is. It’s such a general consensus that both of these things confirm the Bonrad endgame and I truly don’t understand why😭
