Stiles has been your best friend since you started five months ago at Beacon Hills High School.

Stiles is a recovering meth addict.

Coming down from a high, extremely moody state, he is literally sensitive and he is currently 17 years old. He's been clean for a month, but today he looked paler and more restless.

You're at his house doing science work with him at the moment, while the two of you worked on drawings for the science posters.

"I need to go drink water, I'll be right back." Stiles says so.

Stiles left and you continued drawing and researching on the LapTop but Stiles came back looking dazed and even paler and it was there that you noticed what was happening.
