What Did Damon Say To Katherine? (Something About Forgetting The Past 145 Years?)

He said he had a question(the question being does she love him) and then he said
"answer it right and I'll forget the last 145 years i spent missing you"
because he knows that she was out of the tomb but didn't come to look for him and he's saying he'll forgive her for that if she answers the question right.
He did NOT call her Elena. What he said was "okay wait" which sounded like "Elena" in mid-kiss.
