The night Ruth aimed a gun at Leena, she gave a hint to Heather. At that crucial moment, Heather was only concerned about her daughter's safety, so nothing mattered except rescuing Leena. But Ruth planted a seed of hope in Heather's heart. She couldn't properly sleep for the entire week, knowing that someone out there knew the truth about Leena's biological father.
The cruise ship investigation had not worked in her favor either. Considering the number of people boarded, Heather found it complicated. If Francis had helped her, it's not a big deal to find Leena's father with his influence. But he is blocking her investigation instead of helping her because the man's jealousy has reached Everest. She thought of asking Devin, but without a beat, he will tell Leena. So, she chose Kurt and pestered him until he agreed.
