SPOILER WARNING: This article contains spoilers for “Monster,” the latest episode of “The Flash.”

On tonight's episode of "The Flash," the new Harrison Wells was revealed to be a fake scientist. While he was a vital part of S.T.A.R. Labs on his Earth, he was actually more like the public face of the Lab and not the brains. This revelation came after Cisco and Barry discovered HR's self-recorded voice memos, which were HR's notes for his forthcoming book. HR apologized for lying to the team and they agreed to let him stay if he remained one hundred percent honest with them moving forward.

HR's true intentions weren't the only reveal during this episode, as Julian Albert got honest with Barry about why he moved to Central City to study metahumans. After almost killing a kid, Albert confessed to Barry that he was scared, like the kid, and felt powerless back home in England. He admitted that he didn't know anything about metahumans, and was not an expert on them. He also revealed that he was from a wealthy family in England and was jealous of metahumans because he wanted powers to do good on the Earth.

HR and Albert's hidden identities also mirrored the journey of episode's main protagonist -- Caitlin Snow -- who came face to face with the "killer" side of her powers. After her mother's assistant Nigel tried to kidnap her and use her, Caitlin almost froze him to death. Her mother intervened just in time and reminded her that she wasn't a killer. Caitlin's frost powers are being explored in a huge way this season, and so far her mother is the only person who knows about them. At some point she will need to get honest with the team just like HR and Julian.

HR also alluded to the next episode of "The Flash" -- which is titled "Shade" -- when he asked the team if they had ever "shaded the truth for what you believed to be the greater good?" Almost everyone on the show is shading some form of the truth this season: Caitlin is shading the truth about her powers from the team, Barry is shading the truth about being The Flash from Albert, and Barry is also shading the truth about Wally's Flashpoint powers from him -- which he will start remembering in the next episode.

Starring Grant Gustin as the Scarlet Speedster, “The Flash” airs Tuesdays at 8 pm ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
