Alex Moyer is a pre-made Sim from the tutorial in The Sims 4 that was added in patch 73. Alex serves as the player's roommate before moving out at the end of the tutorial. During regular gameplay (either after the tutorial or after the player skips the tutorial), Alex is a regular townie in her own household. Additionally, Alex never ages, even if she is added to a played family. The reason of that is because Alex is not playable, she is controlled by AI. She will remain on her first day of young adulthood forever.
