Do Du think that Slade, Shado oder anyone else from the island is alive? and would they Mitmachen Arrow? and how would he react?

Yes,Yes, and i hope so

Shado's alive, because I'm 90% percent sure she's the blonde in the leather clothes. She's obviously wearing a wig. I hink Slade's alive, because Manu Bennett was promoted series regular, wasn't he?

Shado is must have alive and Slade must have been working with shado too because she alone cant handle the whole operation of helping the arrow.

Slade is alive. Shado is dead. Sara is alive. There ya go.
