At some point after their adventure in Libertalia, Nathan Drake and Elena Fisher started a family. They later bought a Labrador, whom they named Vicky. After a reference in one of the games saying they will name the dog after Victor Sullivan. The dog grew up with Nate and Elena's daughter, Cassie.
- Vicky's eventual appearance was alluded to in "Hidden in Plain Sight", during which Nate mentioned to Victor Sullivan that he wishes to buy a dog, to which Sully replied by offering to buy it.
- Her name, Vicky, is also a reference to Nate asking Sully if he could name the dog after the latter, to which Sully agreed.
- Vicky appears to be between 9–12 years old, based on her pink nose (Labrador noses tend to turn from black to pink as they age), her adult size and photos showing her as a puppy/young adult with a young Cassie.
