1. Thea- I highly doubt that Thea is going to die considering if this was the route the producers would take, it would have been done in Season 3 where what’s his name stabbed Thea in her living room, and left her for dead.
And Thea is actually my number one choice at the moment. Her or Felicity would be the biggest blow to Ollie but I don’t think they’d go and break up Olicity by killing Felicity. That’s ending their show, really. The fandom would never return. But Ollie’s rasion d’etre has always been his little sister. He just started accepting that he can walk in the light and always be in the dark. What better way to show him that there is peril in the light than by his sister’s death. Also, 10 cookies says it was Merlyn.
Yeah, if its Thea, I can definitely see this as a way to reintroduce darkness back to Oliver that would sort of take him back to his Season 1 Days, and if they wish to reintroduce Roy, they could have him come back to take over his role as Speedy/Red Arrow while also helping Oliver grieve.
The producers killing Felicity would definitely be a dangerous route to take, but they’re speaking of bringing stakes back to the show, however I wonder if they’re brave enough to venture into what would then be considered war territory.
My first choices, I’m stuck between Felicity and Diggle….second choice, I’m going with Thea.
