TH, not TH, PDA, mistaken identity - whatever - I still think they have each other's genitals on speed dial.
I think she was in HI more often than that one time. I think they saw each other in LA when he was returning home from HI. I think they very well may have seen each other - outside of the obvious promo work - in LA when he arrived from Vietnam.
However, I don't believe OK when it says that he wants to take 'the next step;' they both seem happy with the casual thing. And if they do decide to debut, they've both been so non-committal and evasive with their denials that they could work around the 'but they lied to us' outrage with ease.
