Wonderful story! I love (of course) that Peter's figured it out, and that Broyles suspects somethingn even if he isn't sure exactly what. That Peter's able to "find" Olivia like that, and that his presence calms her down and focusses her.

And this made me smile:

Walter looks vaguely hurt. “You had some without complaint.”

“That was before you told me it had LSD in it.”

Peter looks at the ceiling. “I’m so many kinds of not surprised.”

Such a Fringe moment. ;)

Great work!
