Ohh yes. This is two of many instances we could easily detect what Clark felt for Diana ( and vice versa) was deep, complex and tender.
A League of One is full of moments! I will add a couple more. And let me tell you, I have male friends. Good ones over the years who are like brothers to me but no way I expect this sort of stuff from them. It is too intimate and too tender. This is not platonic. This is love. It is love that cannot be for reasons as you listed above but it is love. It is on another level. It is is unconditional and sacrificial.
“Then I will go with you. Together we can defeat…”
“If you go with me, we both die. Why would I have sent three of my team mates, my friends, into deadly danger? If you insist on coming with me, you sacrifice them. It was a terrible thing to do to you, Kal. I am sorry. But the world can’t afford to lose you.”
The tears in Clark's eyes when he tried to resuscitate her and he though she might be dead. "Diana...Please." Such emotion! I wish Chris Moeller would write a smww story or JL story again.
Many stories it is Diana who is the one to break Clark from mind control because she always was an avatar of truth and carried a tool that makes people speak the truth. REAL TRUTH. Not half baked truth or omissions of truth. She always reminding him of his goodness and greatness. And often he is the one to remind her. It is funny whenever they needed counsel or support OTHER League members know who they need.
A Midsummer's Nightmare. They sent Clark for Diana. Because they knew their bond.
“How can I trust you, Mr Kent, if that is who you really are?”
“You know you can. You
know.
JLA Pain of the Gods. J'onn knew who Diana needed to support her emotionally. It was Clark. Remember the line about missing her so much he would turn time for her?
During Our Worlds At War, I swear, if DC Comics was a tv series, the audience would want Diana with Clark. This event showed a connection these two had that no one else had.
From her understanding how he was feeling, telling him it was okay, giving him strength to shrug off their losses and forge ahead. She did not whine about what he did or did not do or who she missed like someone else. His feelings for her , made him react to her in ways he did not with anyone else. Like not seeing the others injured in space and only seeing her and not even hearing anything else but thinking he was seeing her fall to earth. Maxima was telepathic and she sensed how much he cared. She said it specifically of her. "He cares for her.
That one." Aquaman misunderstood and in his usual surly way was like..."Of course we all care for Diana." You had to be blind not to see as a reader not to pick up on the hints left by Loeb.
The Oblivion and, The Asgard stories...all tried to suggest Superman was so in love with one woman he'd never move on even if he forgot everything about her...but imo there was enough to cloud that conclusion. I mean some people like to suggest Clark rejected her. I would say well, sure but he was damn sad about it. after Asgard , the handing over of the Mjolnir ( one wonders...did he make it by hand for her???...the thoughtfulness behind that but the sentiment) and conversation showed that they still had something very deep . After Oblivion, Diana's Garden of Dreams had that life she remembered as part of her subconscious. Even when Batman told them what they were living was not real...Clark admitted he wanted it to be real more than anything. Those were his words. They both did. But they understood that they had lives to get back to. It was a sacrifice they had to make.
I recall Waid's JL run. Dwayne Mcduffie's. Even Kelly who tried to push the WWBM stuff...Clark and Diana remained close and there were moments of connection. Hell Mcduffie married them in an alternate timeline.
And Clark had moments where one would see regret or jealousy.
I could go on and on. But it was all there.
