there is a consensus that oliver's death is one of the saddest.

near the end of season 6 he was on trial for being the green arrow. he admitted to his lawyer, jean loring that he was the green arrow and jean suggested admitting it. oliver said he can't because he never planned on being the green arrow for the rest of life and that he actually wanted a life after being the green arrow. if he admitted, it wouldn't have been possible at least he thought. end of season 6, he did end up admitting it and that put his family in danger. and he died as the green arrow so he never got to live his life without the stress and burden of being the green arrow, other than maybe at the end of season 7 but he had to return as green arrow.

Did she want to say to Thea that he is her father or that he is alive?

I had a dream where I was Oliver Queen from an alternate reality where he survived Crisis🏹

Malcolm Merlyn could be Ras Al'Ghul because:

• Oliver Queen was Ras

• Whoever survived a battle with a Ras Al'Ghul becomes Ras

• During the season 1 finale,Malcolm and Oliver are fighting on a rooftop but then Oliver thought he killed Malcolm but he actually did not.So Malcolm survived!
