AFallout 4 player shares a clip in which Cait floats up to them as if she's swimming through the air. There are many Fallout 4 companions to choose from, and Cait has become a favorite with some players, but this may be the most bizarre thing that she's done.
There are 17 Fallout 4 companions, each with their own specialties and storytelling possibilities. As companions will approve or disapprove of a players actions, some incorporate certain ones into evil or good playthroughs.
Cait becomes available as a companion after the Combat Zone near Boston Common is cleared and the player talks to Tommy Lonegan.
The NPC has a background in cage fighting, and she will use Psycho, Jet, RadAway, and other Chems in encounters, making her particularly useful.
One gamer has spotted Cait acting bizarrely as she follows them, swimming in midair rather than running to catch up. Reddit user BudderTheLordOfCarbs recently shared a clip of Fallout 4 companion Cait following them from behind a building.
