Harker walked on his way home. The kids had stayed with the Tariqs again after school, and he does feel slightly guilty for having them take care of his responsibility for him.
But he also learned the hard way that there were just things you couldn't change, and you could choose to mope or to think of a way to improve it. So he chose the latter. This would be a one-time thing, he won't be like his dad who would just leave behind the three kids with no warning or an explanation.
He does understand why his father must leave. He doesn't know everything, but he understands it.
They were basically doing the same thing. Doing what they believe was right as discreetly as possible because they want to protect everyone else.
So it would be hypocritical of him to judge his father and his disappearance. He just wished he wasn't kept in the dark so much…..
