NPC
Rattina
Updated:
Ratthew's missing twin sister — disappeared from Animal Corporation. Fan theory: she is the Stalker enemy.
Overview
Rattina is the missing twin sister of Ratthew. She used to work for Animal Corporation — duration of employment unknown — and disappeared without a trace at some point before the player's arrival at the hospital. Ratthew has been actively searching for her whereabouts since, which is the implicit personal motivation behind his entire Shadow-experiment investigation.
She is not a directly interactable NPC. Players encounter her primarily through references in Ratthew's dialogue and via her picture in Ratthew's quarters. Next to her picture is the note 'the Shadow now sees everything' — the same key reveal Ratthew hands the player about the Shadow experiment. This visual placement directly connects Rattina's disappearance to the experiment, which is the most lore-substantive thread in the game.
⚠️ Spoiler warning: the Fandom page documents a widely circulated fan theory that Rattina IS the Stalker enemy. The visual and contextual evidence is substantial; the confirmation is not.
Appearance & Design
Looks almost exactly like Ratthew, with two distinguishing additions: visible eyelashes (Ratthew does not have eyelashes) and a purple bow tied on her right ear (Ratthew's ears are unadorned). Otherwise the body silhouette, the white snout, the buckteeth, and the long curled pink tail are identical.
The near-identical appearance is the structural basis for the Stalker fan theory — the Stalker enemy is a tall black rat figure with similar facial features, and the visual overlap with Rattina is unlikely to be coincidental given the placement of the 'Shadow now sees everything' note next to her picture.

Notable Traits
Limited documentation. The Fandom page records her as 'the smart one of the family' per Ratthew's framing, but no direct character interactions exist in the game. The gender is documented as female (she/her); the species is unknown despite the visual identity with Ratthew (rat).At a Glance

Story Role & Lore Significance
Rattina's story role is structural rather than interactive. She is the missing-person anchor that motivates Ratthew's investigation, and her presence (via picture and dialogue references) provides the emotional weight behind the otherwise abstract Shadow-experiment lore.
The disappearance from Animal Corporation places her inside the same research framework that Dr. Harlow and Ron from Accounting both circle. If the fan theory is correct and Rattina IS the Stalker, then the Stalker is the in-game manifestation of an experimental success — a former employee transformed into the watching-presence enemy that haunts the hospital. This would make her both a victim of the corporation's research and an active gameplay threat the player has been encountering without realising the connection.
Fan theory evidence: visual similarity between Rattina and the Stalker (both small black rat figures with prominent eyes and grins), the 'Shadow now sees everything' note placement next to Rattina's picture, the Stalker's name (a 'watching' presence aligns with 'sees everything'), and the timing alignment (Rattina disappeared from Animal Corporation; Stalker is one of the hospital's persistent passive threats). Counter-evidence: the Stalker's appearance is canonically tall, while Rattina is described as small like Ratthew. The size mismatch is the main hole in the theory.
The confirmation is not present in any documented Fandom or official source. The theory remains theory.
Trivia & Hidden Details
Name is a pun: 'rat' + the human name 'Tina,' following the same naming convention as Ratthew (rat + Matthew). The matched naming reinforces the twin relationship.
The Fandom page is marked stub — Rattina is genuinely under-documented at the time of writing, which fits her in-fiction status as a missing person whose history is fragmentary.
The purple bow on her right ear is the most distinctive visual identifier. Players hunting for the Stalker fan-theory confirmation often look specifically for whether the Stalker has any purple bow remnant or analogue — none has been documented, which is another hole in the theory.
Documented gender (female, she/her) is one of the few cases in the NPC roster where gender is confirmed rather than left as 'unknown.' The specificity matters because gender is often unconfirmed for AH characters; for Rattina specifically, the female framing is part of the in-fiction sibling relationship with Ratthew.
