Owen's forgiveness hug in End Of Days
Check out the expressions: Owen's concern and trepidation just beforehand, contrasted with the sweetness and affection on Jack's face once he's actually touching Owen. Look at the strength of Jack's hand around the back of Owen's head. The body language is much more sexually charged and intimate than the kiss with Ianto that precedes it, and keep in mind that Jack has to physically extricate himself from Ianto's grasp to get to Owen and this beautiful moment.
