This was a very sad and painful episode, not for just Clark, but for Martha. So many hopes and dreams were dashed when she lost her children, yet through it all she and Jonathan weathered the storm.

Clark was fortunate to have been found by them.
Yes, he was. He was found by two people who were willing to take him in and raise him as their own, despite not knowing where he came from, and who continued to stand by him when he developed some very strange abilities. None of the Kents' biological children lived, but they had room in their hearts for a strange child, and even when he came back from the Games changed, he was still their son and they still loved him.

"Oh, you can’t help that," said the Cat: "we’re all mad here. I’m mad. You’re mad."
"How do you know I’m mad?" said Alice.
"You must be," said the Cat, "or you wouldn’t have come here.”
