Lacey meets Peter purportedly for the first time here, yet they had already met when Lacey interviewed her mom's coworkers in 1.5.
it appears that perhaps 1.5, (given the interactions between Lacey and her mom,) was added later, filmed after 1.7 was already edited, and they just didn't bother to fix 1.7's story-line with Lacey to conform to Lacey already having met and interviewed her mom's featured coworkers.
Dr. Hunt also makes reference here to events of 1.4 as if that was the last time she and Lacey had seen each other, as if the events of 1.5 hadn't taken place.
This is 1.4 so none of this is correct information.
