Submit your own characters. You can make the kids any age you want. The kids can be related to both parents, adopted, or related to only one of the parents. A few examples of the kid being only related to one of the parents would be if Spencer had a kid with Andrew but ended up marrying Toby, Hanna has a kid with Travis but ends up with Caleb, or Aria has a kid with Ezra and ends up falling in love with Jake.
Submit the general things like parents names, their name, age, gender, personality, appearance, Relationship with the parents, Relationship with potential siblings, and relationships with the other liars potential kids. Also include some possible plot points in your submission.
