having arya and the hound ride together from winterfell all the way to kings landing, and only at the final moment the hound tells her not to go through with it... and she just says "ok"
i know we've been wanting cleganebowl for a long time, but that fight had no purpose other than fan service. tie it to the goddamn plot somehow. for instance, arya is going there to kill cersei. instead of bailing on her mission, you have the mountain get in the way and slap her around, only for sandor to come in and take him on, allowing arya to proceed. defending her one last time. she could say the whole "sandor, thank you" thing right then as he's about to duel his brother. and it would be a callback to syrio saving her from trant's men as she escaped. man... its like they allowed their children to write this season
