First it was a delightful part. The visit to Smallville was great.
The Lois flashback was wonderful.
OK now comes the rant, feel free to stop reading.
“Thanks, Clark,” Superman said quietly. It felt nice to go through this with someone who really got what this felt like this time around.
What? I find this line jarring. The first time around Visiting was Clark & Superman, he was full of doubts, deep terrible self doubt.
But we didn't see your Clark going thought these doubts.
Clark shook his head, trying to clear it of all the confusing thoughts.
Your Clark is confused. Later you wrote "feeling discouraged". But he is not ripped by self doubt because he is not Superman and anyways he knows the problem was over come or Visiting would not still be functioning as Superman.
As for your Visiting Superman, he is clearly upset
BUT this time he has no reason for doubt or soul searching because he already knows he is not causing the heatwave!!!!!!
This puts him in a completely different place emotionally!!
The very first time I had a patient in my care die I was in deep emotional pain. Even after the ME and my medical director and the department head and my DNS all assured me that I had done everything I could and I had sat through the M&M review I still felt bad about it, for no valid reason, for months.
If I was transported by time to 1979 and had to relive those same events today I would still feel bad about the death but I wouldn't be eaten alive by self doubt.
So I can not see how Visiting could be feeling anything like he was the first time.
So neither Clark nor Visiting are feeling what Visiting was feeling the first time.
If anything your Clark is denied a growth experience. However your Clark already has so much self doubt that he doesn't really need any more.
So back to the point I find it jarring because they are NOT IN THE SAME EMOTIONAL SPACE.
