I love the latest development that Oliver wants to ignore the possibility he is a father. It makes the character so much more real. Oliver is a great guy & I love him, but the fact that he'd rather pretend he isn't the father, instead of step up & take a DNA test is a flaw that makes the character human. As a young gay man just coming to terms with his sexuality he doesn't want the responsibility of being the sole parent to a baby. Its natural & understandable, even if it isn't the most honourable thing to do.
I can't wait to see how this story plays out & how Oliver reacts when he finds out Kyle is finding out definitively if he is indeed the dad.
