can آپ help me figure out whats going on?!

Well right now in storyline of the show.

Damon isn't in love with Elena, they are
just friends.
Damon کہا he came to torture Stefan because
of Katherine, and Katherine is the one Damon
is in love with.
He tried to free her from the tomb, but found
out she hadn't been in there at all.

Hope this helps at all
