Christine and Barry
"It is a big decision," Barry agreed. "Even if we are going to let Arva raise the baby." He would still be making some kind of commitment to Christine, at least for the three months that she was pregnant, because he wasn't going to let her go through that alone. And they would both have to live with knowing that they had a child on the island who was growing up without them.
He smiled. "I like you too," he said. "And if I am going to do this, you're someone I'd feel comfortable with." Apparently he had a thing for medical professionals - first Martha, now Christine. It made him wonder about his true feelings for Caitlin, but he shook that thought off easily.
