Final Episode?
I loved watching Superboy when I was a kid. I remember the last time I saw it, some alien came to Earth (if I remember correctly, he claimed to be Kal-El's brother, so possibly Mon-El) and convinced Superboy to leave Earth with him. All the people of Smallville gathered around as Superboy left in a cliffhanger ending. Then I never saw another episode after that.
Was that the series finale? I always hated finales like that (same with Lois & Clark where they got a baby, but never explained how).
Thanks in advance.
