Sam and Katrina had a kid. BornIn 2019 named yn

skip forward in time to the present Sam and Kat had broken up and they shared custody. However this made yn slightly distant from them and closer to Colby (Sam's best friend) since Valerie thought anything she said to Sam and Kat would be used in a fight between the two. Yn is only 5 so Colby started to be her comfort person. Especially when Katelyn (Sams new gf) comes round.

*Yn was sitting playing with Sam until there was a knock (Katelyn).
