Third person's POV
Since Derek took Tabitha and John back in a hurry from the island, he hadn't paid much attention to Klein.
According to Alvin, Klein had already returned to Canada and showed no intention to come back to Seattle to steal Tabitha away from Derek.
That was to say, to Klein, Tabitha was just a temporary fling or a plaything—no feelings involved whatsoever.
At the realization, Derek was both angry and upset.
Tabitha was the love of his life, yet apparently, she didn't receive the treatment she deserved from the father of her baby.
Derek was confused about how to deal with Tabitha. These days, even though he tried to convince himself to accept the baby, he just couldn't.
No matter how hard he tried, he couldn't bring himself to treat the illegitimate child as his own.
