So I can see not having someone end up paralyzed after falling off a horse but are they supposed to not have any storylines that could potentially be related to anything someone from any Superman show or movie did / was involved in?
Superman's comment to General Lane about trust going both ways gets more and more ironic as he keeps holding back from telling Anderson Anything, about what's going on or what they're up against. Watch the entire episode, if Superman had told Anderson literally anything about the threat, about what Bizzaro was and what they were facing this would never have happened. But he held back because 'if we tell him he's just going to send in the Supermen of America'. Irony.
If he did we would have just hated anderson more because he wouldn't have listened anyways the problem here isn't that Clark doesn't trust anderson, is that Anderson doesn't trust clark because he doesn't want to submit to him and "America" (he just uses the country as an excuse let's be real here)
