Alexa is a midwife and occasional date of Mark Scout.

Alexa helped to deliver the baby of Mark's sister Devon Hale.

Alexa appears to be a kind and empathetic person. She encourages Mark to talk about his experience being Severed, and is open to hearing him reminisce about his late wife Gemma.

Alexa seems to hope that the relationship with Mark will become more serious than it is, but Mark is unable to commit further, largely in part to his continuing deep grief resulting from his wife's death.
