There are tons of moments.
Pre Crisis. The time Barry notices the look on Kal's face when Diana leaves the League and mentions he always felt they would marry one day.
Eros hitting them with arrows. Lol that was hilarious. And very cute.
Then Post Crisis/ Preflashpoint.
Their "date" .
Clark coming to give Diana some support and fixes her cape and her telling him she would always love him for it.
There is a comic where they meet up as Clark and Diana in a park. It's rather sweet and wistful interaction.
League of One has tons of moments. And yes the one where he resuscitates her , (his face when he thinks she is dead) and then their talk.
Midsummer's Nightmare. The JL forget who they are and think they are regular civilians. Clark is sent to wake Diana up. She is a school teacher and he puts his hand out to her to step off a balcony to him...she asks him how can she trust him...and he says...you know. She puts her hand in his.
Our Worlds At War. There are a number of very telling smww moments in that event. Some are one panels , other a page or a moment but it shows how important they are to each other and how much SHE understands his burdens and responsibilities when he is faced with having to be the hero and sacrifice. From her telling him to not worry about what came before and to just focus on what was to come, him carrying her injured to Hippolyta, to him thinking she was dying, to him and her attending a memorial etc Just moments where you can see that in times like those Clark needed Diana and vice versa.
Clark comforting Diana after Hippolyta's death.
Clark and Diana sit on a roof I think after Batman's death and they talk about their mortality etc.
Sparring scene where he says she never ceases to amaze him.
There is an issue where she is with Superboy and they look after an injured Clark and then all three fight the baddies together. Some cool moments
Pain of the Gods...the story does show an angle again when they are each other's main emotional support and even J'onn knows this.
Circe mind controls Clark and Diana fights him. There are many stories actually of Diana and the lasso able to get through to a mind altered Clark.
Spirit of Truth. Their scene where they talk about their missions and goals etc and share coffee.
Kingdom Come...That farm yard scene, the passion scene, the marble scraping steel scene, the giving him his glasses and kiss and the Epilogue.
The New Frontier. The flight in the sky and talking about leadership. The "there is the door spaceman"
Dk3. The reuniting scene after the big battle. Kal kissing her while holding jonathan
The Kingdom. The birth of jonathan.
Distant Fires. "Nothing to blush about darling", scene
New 52.
Those that Lovestar mentioned esp the I love you one.
The gift of time
Double date with Mera and Arthur. The page where they get late in that Annual.
The story by Fisch was good too.
Clark catching Eros bullet in the Valentine's Day Special.
Clark dealing with Apollo and the Gods.
The Clark/Orion encounter was fun too.
The kiss in the stadium. Chasing the plant lol. The ending of issue 12
The scene where she tells him to go and bring DD head. lol
Breakfast in Smallville. The walk in the field. Batman perving...lolololol
I liked the way Diana supported Clark in Trinity War.
I did not like the way Tomasi brought in necessary tension but Diana's whole supportive attitude in Truth was good even if Clark behaved ooc at times. Issues 18 19 and 20 were strong The lying in bed and being his sentinel was a great moment as was flying him and taking out the bullets etc.
There are so many moments through out the decades. Makes you realize how already humanized they are just by being themselves because they are good kind people with a conscience and being connected as friends, allies and lovers.
