Watching a tv-series I saw this line :
1- "I always wanted to be there when they execute your sister" (Context: The owner of this line now believes the execution to be a small chance.)
I suppose using past simple could be correct because of sequence of tenses .
2- I always wanted to be there when they executed your sister. (But when I write executed, it seems little awkward to me because execution hasn't been done yet. I think using past simple imply as if execution has occured.)
So which sentence is correct in this particular context?
