'Arrow' Unthinkable: Is That A Creepy Spider In Thea's Hair?

*Shudder*

Okay, we're pretty sure this is just some freaky clump of hair and a fingertip, but once you see a spider, you always see a spider. Thanks to Redditor faywashere for spotting this and posting it to the Arrow subreddit.

Around the 18:16 mark when Roy embraces Thea -- an object with appendage-like whisps comes into focus for an instant. The creepy crawly-esque entity appears to be about the size of a dime and hangs much like a spider would, upside down, presumably from a strand of silk.

Watch for yourself and leave a comment. Don't blink it's really quick!

The jokes are flying about a Spider-Man tie-in, but we're not holding our breath for a Marvel/DC crossover.

Will the "spider" make a return? Watch "Arrow" season 3 this fall on CW50.
