More eligible stories made this one a bit more challenging. Some of them I knew right away, but I do admit to having to search around for the others.
1. "Seeking Friendship" by Lieta - Guilia was an old girlfriend, so that name in the quote certainly helped!
2. "I Knew the Truth" by bakasi
3. "Superman GO" by Deadly Chakram - Thanks, Pokemon, for making my son get some exercise last year!
4. "Clearing the Air" by NostalgiaKick
5. "End of an Era" by Terry Leatherwood - a look into the mind of Lex Luthor
6. "That Old Code of Ours" by Lieta
7. "Muddying the Waters" by NostalgiaKick
8. "Airport" by Morgana - Where else would Ailieanor Airlines depart from?
9. "Proposed Ignorance" by Deadly Chakram - Mayson knows the secret before Lois does
10. "The Real Me" by CLeuch
Thanks for putting together another quiz! I had fun working it out.
