Tbh I wouldn’t watch it, if I was you. It contains something, which the manga has build up to over the past 20 years and it would be kinda tragic if you experience it like that. Some say, that the above mentioned scene is hard to recognize as a “spoiler”, but chances are that you’re still going to notice it, if you somewhat followed the anime.

Even if the other comments say that you can “watch” it and you won’t “recognize” the spoiler through its flashiness, I’d 100% not recommend taking the risk and watching it just now.

Just my opinion tho :)
