Appearance

Ratthew is a small black rat. He has a white snout, two white buckteeth, and a long, curled pink tail. Interestingly, his ears resemble those of a rabbit more closely than a rat's. Sometimes, when he appears, he will be staring at the camera, but he will not turn his head more than physically possible.

Background

Little is known about Ratthew's background. Based on dialogue with Ron from Accounting, it is known that Ratthew once entered Ron's office. According to Ron, he chewed through reports of an experiment that Ron was not supposed to see. During his first interaction with the player, Ratthew explains that being small has its advantages, as he hears and sees things others do not. According to him, this makes being small a dangerous job. At this point, his identity is marked as "???", as the player does not yet know his name. The next time Ratthew visits the hospital, he tells the player that he thinks they are a good person. Trusting them enough, he reveals his name and advises the player against trusting anyone in the hospital. During the fourth encounter, Ratthew tells the player that he is starting to like them. He explains that many people believe he is an anomaly and expresses his sadness about being treated that way. He expresses gratitude that the player treats him like anyone else. Ratthew later returns and tells the player that he needs to disappear for a while because the Animal Corporation is after him, but that he wanted to speak with the player first. This may explain why he was chewing through experiment reports in Ron's office; it suggests that Ratthew knows the corporation's secrets, and that the corporation does not want him revealing them. After this conversation, Ratthew speaks with the player in the Reception Office. He reveals that he once had a twin sister named Rattina, whom he says was the smart one in the family.

Personality

comes off as paranoid but kind-hearted. He seemingly has a lot of distrust that stems from past experiences. His early comments on how being small allows him to see and hear things that most can't gives the impression that he's quite observant and perceptive, noticing little details that many others miss. Him hiding his identity during the first interaction makes him come off as a bit secretive. He appears quite cautious, as he warns the player not to trust anyone, especially those carrying suitcases, and he later tells the player he has to go into hiding.

Relationships

Main Article: Ron from Accounting According to Ron, snuck into his office and chewed through some classified documents Ron wasn't meant to see. Ron was shocked, but thinks that did him a favor by doing this. If Ron checks in during 's chat with the player, they share dialogue and Ratthew teases him a bit. They seem to be fairly close. Ron has never used his real name, instead calling him "that rat". Ratthew's teasing dialogue towards him can also come off as rude, further hinting towards this. does not introduce himself at first, likely due to his distrust with anyone in the hospital. After the second encounter, he formally introduces himself and tells the player(s) to not trust anyone in the building. Before his final departure, he opens up to the player(s) about his sister Rattina and what happened to her, as well as giving the player(s) a special key that reveals some information about her.

Main Article: Barney Normally, Barney and Ratthew will never mention each other to the player, indicating that they do not personally know each other. However, in the rare case where the player has Ratthew sitting on the counter while Barney is hiding with them, they exchange a small bit of dialogue, after which Ratthew warns the player about him. It is still unknown if they actually know each other.

Known Bugs

Rarely, Ratthew can spawn multiple times, one leaving the hospital and the other checking in. Similarly to Ron, Ratthew can also soft-lock the game (Citation Needed). He, along with Ron, cannot faint or be targeted by anomalies except the Bed Monster (Citation Needed).

Trivia

Despite his height, Ratthew is an adult. Ratthew and Barney are both friends with the player, but Ratthew likes to confide in the player, unlike Barney, who only uses the player for favors. His name is a portmanteau of "rat" and the name "Matthew". Ratthew is the only recurring character to maintain eye contact with the player. The only other characters that follow you with their head are Anomalies and the Shopkeeper Nurse. Ratthew is both literally a rat, belonging to the rat species, and figuratively a rat, snitching on the Corporation with his knowledge of their secrets. If an Anomaly tries to check in while Ratthew is sitting in your office, Ratthew will say something about it in red text. He, in a similar vein, warns the player about Barney when he's at the window, saying he's untrustworthy and advising them to get the taser. Despite this, Barney cannot be tased or shot. Ratthew is homeless, and it is implied that he may be living in the vents of the hospital based on dialogue by Dr. Harlow. It's unknown if Ratthew and Barney have known each other prior to their interaction at the hospital.
