Damn, this was actually really really good. What year was this?
Let me count the good:
1) The story progresses logically, with minimum Silver Age lunacy. 2) The Clarks make the logical assumption that the two kids in the rocket are brother and sister. Again, logic! It's perplexing that they would actually split the family up, but it's actually genuinely justified. 3) Lara is the superhero. 4) The family knows who the superhero is. 5) Genetic fingerprinting! A far fetched notion! Awesome. 6) Jack Kent figures out who the superhero is from the "subtle" clues she drops.
