Baby Loring was conceived in a one-night stand between two eleventh-graders. Not yet ready to have a child, his biological mother Juno first wanted to abort him, but then decided to have him adopted out. Vanessa Loring was going to adopt him with her then-husband, but he left her, so she adopted him as a single mother. Juno and Paulie both seem to have some regrets about it, but they know that it's best for him.
- His step-grandmother, Bren, was there for his birth, along with Juno's friend Leah.
