Love how the plot is developing
Just keep in mind, that whatever the reason was for not telling you, your parents still loved you and raised you as their own right?
Jett I love you for being so understanding and making Kyle look differently at his parents and dissipating his anger
Not telling them early enough is good because growing up you have all different stress in life why add a huge one
Yes they did not tell but was there any benefit for them other then giving unconditional love to both the adapted kids
Kyle you are a good person and don't let your relations with loving parents be strained, look at the love and life they have given you and be blessed
