omg remember episode 2 of season 3, when aria received the earring? and assumes it was merideths, but merideth denies it was hers. when we see ali and aria trash byrons office, ali is laughing when aria finds the earrings. i bet anything theyre alis!!
Those earrings could very well be Ali's, good observation! A motive for Ali planting the earrings could be an excuse for Ali and Aria to trash Byron's office. And a motive to trash Byron's office just may have something to do with Garrett's story about the night Ali was killed (as told in the Halloween Special 3.13 "This Is a Dark Ride"). As we recall, Garrett mentioned Byron as the last person to see Ali, and the latter two seemed to be having an argument. Byron had told Ali, "You say all these grown-up things, but you're just a child." Although the reason for Byron's remark remains unknown, we can still speculate. As mentioned in previous theories, Ali could have been blackmailing Byron. Or perhaps she herself was having an affair with Byron (though that seems a little far-fetched and disturbing since Ali is the same age as his daughter). Either way, Ali had something against Byron. How could she pass up a chance to trash his office? Altogether Ali was one to get involved in other people's lives. There has got to be more than we think to her twisted story involving Byron...
