Arrow: Reddit Found the Killer Months Ago

Warning: Spoilers ahead for tonight's episode of Arrow.

Tonight's episode of Arrow finally revealed the identity of Sara Lance's killer and, to the surprise of probably a healthy chunk of the audience, it turned out to be Thea Queen.

But not to this Redditor, who figured that out months ago by digitally decoding the voice on the rooftop the night of Sara's murder.

Here's the result...

Certainly it wasn't 100% clear that it was Thea -- and of course anybody who distorts the audio looking for something is likely to find it, whether it's on the money or not...but certainly it's kind of cool to look back at October 22 to see fans digging up forensic evidence in support of tonight's finding.
