I wonder if in the past he only could feel only Sarah or it was different with everyone for him?

I think he could. Duke kept his trouble, even in the past so I assume Nathan kept his, too. It was hilarious when Sarah was dragging him by his ear and he kept going "ow, ow, ow, ow". Teehee.

I like Jordan as well, not that I care for her and Nathan as a couple but she doesn`t deserve being manipulated like this.
