^ we were led to believe that Jason was Kenneth's son too but he wound up being peter's. That being said: he is the half sibling of Spencer, Alison, and Melissa. And Charles. Melissa and Jason are half siblings and kissed, but many people don't refer to someone as their "half sibling" (at least not that I'm aware of, they just say "my brother"/"my sister").. That's incest.

Toby and Jenna were step siblings.. Also considered incest.
