Bonjour !
I'm delurking to tell you how awesome your story is.
You sneak into LL's mind accurately and frighteningly, to the last down-to-earth tidbit... I was torn between a smirk and incredulous astonishment when he thought Superman would rescue him. How typical. After all Lex's attempts to kill him, and knowing Superman was well aware of it, too! In a way, it's a back-handed compliment to Superman's values.
For a Frenchwoman whose country has abolished the death penalty, your story was quite chilling... and yet, considering who Lex is and what he did (or ordered it done), this is another kind of Justice.
The revelation at the very end was a kind of poetic justice, an ironic one with very dark undertones, too... and it shows how much Clark was shaken by Lex's actions. This taunt was kind of cruel, in a way, and Clark is anything but cruel... This was enlightening to see how far Clark could be pushed.
Thank you.
PS : I do hope your health will be better.
