As Sean's identical twin brother, I can proudly say that I have 20/20 vision; therefore, Sean can see just fine. The bottom line is that Sean IS a spy, and a shitty one at that.

Sean's Glasses: glasses are cool and make you look sophisticated and sexy. even if he doesn't need them he should have them. i am not biased on this.

Sean a spy? Not with that afro, my friend. So I say away with the glasses.
Hey, glasses didn't help Jon did they?
Love, mary girard

*Big Bang*

Sean can't read road signs without glasses and isn't observant enough to be a spy. Also he doesn't own enough gadgets or a shoe phone that I am aware of. Although, it could all be a front. He could be hiding secret things in his hair and maybe all that "Lord of the Rings" nonsense is spycode...

*Big Bang*

hmmm, well the first thing he has to do is......... , then maybe , just maybe he can be a real spy.

*Secret drunk guy*

Shitty spy? Would that mean that the spectacle wearing Shawn is an imposter and that the "real" Shawn has been tampered with in some way? That would explain his bizarre behavior of late. I agree, Shitty Spy is my final answer.
*Jug Head*

he needs them to feel seperate from his twin...and he's a spy.

Sean's Glasses: Speaking as the subject of this highly uncomical joke, I can say
that I do really need glasses. However, I have the capabilities of becoming a
spy much easier than you all think or can comprehend. Besides how do you all
know that I haven't been taking pictures and documentation of your personal
lives. Huh?
