This is a love triangle, a pity someone would lose out in the end.
I hope this story has a good ending for Kate, i am glad Seth was willing to control himself there.
I can understand how Samantha may be feeling, but she has to think of Loren, she is also human and needs companionship and intimate love, let her tell Loren how she feels, a mother's love for her child is very different from that for others.
I agree that Love is one of the greatest things (experiences) which can happen to any of us.
