Jeevan
I was so happy for Jeevan in episode 9. Because they kept making it look like he was dead since he was not in future. But he actually found himself happiness and lived a good life.
Losing Kirsten was the best thing that could happen to him. She was too self centric and selfish. He was deeply unhappy when he had to look after her and she was having her "I will do what I want" attitude.
And nothing changed when she grow up.
