I'm inclined to agree with you from the standpoint that I like Ted and Barbara as just friends, but there's been this, their history of cyber-sex in BOP, the scene in Countdown were Ted laments being the wrong guy in blue for her, and then the scene in Formerly Known as the Justice League where Barbara's flirting at Ted and he's missing the point. It seems like there's an undercurrent of effort to make their relationship more than it was.
