Episode 8. Minute 22. The women are tied to a iron bar with handcuffs. The next minute they are not longer tied to the bar, but still have their cuffs.
The teenage Reacher's eye is brown color, but the adult Reacher's eye is bluish-greyish.
In the books, Reacher always used an alias that has the same first letter in the surname and forename as he, such as John Richardson. He does not do this in the show.
