Arrow Season 5 Finale: Predicting Who Lived And Who Died In 'Lian Yu'
15. Black Siren/Dinah/Rene
Black Siren, Dinah Drake, and Rene Ramirez have all proved to be - to varying degrees - solid additions to the series in Season 5. Rene is the most developed of the 'new recruits', Siren gives Katie Cassidy a chance to cut loose and have fun in a way she wasn't afforded as Black Canary, while Dinah - though we haven't see too much of her yet - is looking like a fitting Black Canary herself. Rene had the least to do the finale, since the two Canaries at least got a brief face-off.
Since all three are relatively fledgling presences on the show, and definitely have a lot of room for further growth and narrative importance, it'd be wasteful to kill any of them off now.
But the reason they're all grouped together, and why it's almost certain they'll live, is because they've all been confirmed as series regulars for Season 6. That could be misdirection, but it does seem more likely we'll be seeing them again next year.
Prediction: All three survive.
