In the last second before the bomb blasts off, Clark tosses it from the Daily Planet building, although everything is in slow motion, the Daily Planet logo on the building is rotating at normal speed.
Bizarro absorbed Clark's memories before Clark met Kara, so he should have no knowledge of her.
When it was revealed that Editor Gabriel is Lex's brother Julian, most of the viewers missed the point that Julian was killed in childhood by Lex's mother Lilian, so Gabriel cannot be Julian. Actually, viewers thought he might be Lucas, the other half brother of Lex. Only when Adrian and Julian start revealing the same memories, it dawns on the viewers that he is not Lucas, and Lex has indeed got Julian cloned and Adrian was right all along on himself being the first prototype of Julian. More hints or clarification should have given by the writer/ director for viewers to realize this twist even earlier. By keeping it subtle, writer/ director stole viewers' curiosity about what exactly is happening.
