I dont think thats her handwriting...I have seen her writing on stuff and that does not look like it
Sam is supposed to have long brown hair...but that might have been too much addition to emma or anyone really. that much change could make anyone look everdone, thats maybe why they decided to leave her in a more natural state. the outfit... perks is set in 1991 and 1992 so... she looks good. I cannot wait to see this movie...
Sam is Charlie's love interest in perks. Also, along with Patrick, best friends of Charlie. The three make the "Perks trio"...with a focus on Charlie, of course...kind of the same as HP in that sense.
