Hellen and Ryan have not spoken since Ryan found out that Hellen was pregnant. It was a big mistake for Hellen to lie to Ryan. Either because of her stupidity, or whether she forgot that her husband is a doctor who would know the slightest difference in her body.
Ryan didn't even talk to the woman at all. He didn't want to give Hellen another chance to trick him. Back then, the baby turned out to be John's, and Ryan was so naive that he didn't find out the truth about the baby. Then now, once again the woman dared to lie to him.
Ryan still doesn't understand why Hellen is trying so hard to convince Ryan that her pregnancy is the fruit of her love with the man. In fact, when her first pregnancy fell, she even just left Ryan and returned to John.
