John probably wanted to kiss her. I think we can see him lean a little bit forward in that scene. ;P
But you know... he probably didn't do it because of her. Helen knew he was back to the John she fell in love with, but I think she was still afraid of letting go, after keeping her emotions so close for so long. And I think John knew that, which is why he didn't kiss her before teleporting. ; )
Would be fun to know what thoughts were in their minds at that exact moment.
