oh yeah absolutely!
If you remember back to the very first episode of the season 3B, “Anchors”, stiles is seen wearing this white shirt with the blue collar.
this episode also happens to feature a shit ton of hallucinations and weird shit that seems real to the characters but isn’t actually happening.
If we go over to the next episode, “More Bad Than Good”, stiles is once again wearing the same shirt.
This episode also features a lot of stiles having hallucinations. Later in the episode, he’s wearing this shirt, which you’ll notice is similar, but not the same one.
Fast forward to the next episode, “Galvanize”, where lydia and stiles are investigating the school and the message on the blackboard (which is later revealed to have been written by stiles when he was presumably possessed), the shirt shows up again, but only for a brief scene before switching back to shirt he was wearing for the rest of the episode.
(this grey shirt with the pocket is what he wears for the rest of the episode and)
(a few seconds later, BAM, this shirt pops up again while he’s rifling through the drawers)
(cuts again, a few seconds later, and he’s back to wearing this. That wasn’t a simple mistake)
Obviously, a lot of mind-bending, hallucination crap has been going down, mostly to stiles, and in a lot of instances where it’s happened, this shirt keeps popping up. A couple peeps, myself included, think it definitely has some significance. We just don’t know what. Cut to today, i saw the shirt ONCE AGAIN in these pictures from the set of season 4.
COINCIDENCE? I THINK NOT.
And now Derek’s wearing the shirt.
