Superman v2 #685
Clark: I have to appear to renounce all my ties to Earth. Everything. Including you. Now I used the word “appear.” It would just be for show. You’re my love…and you always will be. […] I said it before, my love. I say it now, and I promise I’ll think it every day after that until I see you again. You have my heart, Ms. Lane.
Lois: And you have mine, Mr. Kent. Please keep it safe while you’re gone and please come back to me.
Smallville: Season 11 “Guardian” Chapter 12
Clark: I can’t go back to the farm, or to work or to our apartment without leading Lex back to the life we’ve built. […] I promise you…I will find a way to come home to you.
Lois: I promise you I’ll do what I can to take Lex down while you do.
Lois: I know that you’re listening. I just wanted to say I love you. And even though just seeing seems like it should be enough, it isn’t. But it’ll have to do for now.
