I wish Delena moments weren't infiltrated like this. I'd call it bad editing to thrust Caroline and Stefan scenes in between like that. Editors could've placed Steroline scene right after the Delena moment ended, instead of interrupting a Delena moment.
It's not about the s*x, its about keeping the moment all Delena wise and getting an opportunity to purely enjoy them without having to deal with any other character or getting distracted with any other BS dished out to Delena shippers.
