Kyle, Summer, and Harrison were once the picture-perfect family, recall The Young and The Restless Spoilers.

Unfortunately, nothing is ever constant in the soapverse.

Thus, the constant turmoil that the soapy drama brings, has broken Summer and Kyle’s love adobe.

Eventually, leaving them in an ugly custody battle.

Both, Summer and Kyle, are currently locking horns trying to get the upper hand in the battle. However, in one of their more recent arguments, Kyle matter-of-factly told Summer that if she takes him to court, she’ll lose the battle. Mostly because she is not Harrison’s biological mother. Moreover, she never really formally adopted him when they were a family.

Thus, Kyle Abbott actually has an upper hand on Summer Newman by virtue of being Harrison’s biological father. But is that really true? Paternity confusions are not unheard of in soap operas! In fact, The Young and The Restless Spoilers recall that the only proof Kye has of being Harrison’s father is Tara Locke’s word.

Back in the day, Tara told Kyle that she had conceived when she slept with him in New York. She assured him that the DNA test ruled her then-husband (Ashland Locke) as the father. Kyle took her at her word and has since lived in the belief that Harrison indeed is his son. But what if Tara lied? Again, paternity lies aren’t unheard of on Y&R!

In fact, there has been so much talk about Tara returning to the soap, that it would be quite an exciting twist! Tara’s return and this unexpected paternity curveball could pull the rug from under Kyle’s feet! So, stay tuned to Soap Opera Daily for more The Young and The Restless Spoilers on this.
