As soon as Lex healed, he looked up at the orange cloud of cosmic dust and felt like cursing it out. Was there really a need to rain on his parade like this? When he became Earth Immortal, he went through so many levels all on the same day. But with this freaky tribulation hanging over his head, he dared not act so lightly.
Lex was about 90% sure this particular type of tribulation was only occurring because he was in the Primordial Garden, which meant if he wanted to avoid them in the future, he just needed to experience a tribulation outside. Of course, Lex would never do that. Why would he run away from a harder experience? More hardship meant more reward.
