season seven has, so far, spent a lot of time tying up loose ends.
so far, the slutty pumpkin and victoria have returned and been eliminated as possibilities as the mother. robin has been once and for all taken out of the equation as of No Pressure.
i'm wondering whether they'll ever mention the woman who ted was supposed to meet up with from Milk again.
i'm also wondering when they're going to bring back sam from battlestar galactica. ted did say "more on that later," but if robin and barney get married at the end of this season, they only have the remainder of it to get back to her secret crush.
it would be interesting to go back and see what else ted has said "more on that later" about that hasn't yet been covered. (robin becoming a bullfighter, for example? Symphony of Illumination)
