As sad as this episode is, I love these two. Because while they might not be real, look at them. They would totally be the children of Robin and Barney. That was the first thing I thought when I saw these two. They are perfect. GODDAMN WHY CAN’T THEY BE REAL. It was a sad episode but still a good episode.
Also, while they did say that she never became an olympic pole-vaulter, which yes, could imply mother as well, they never actually come out and say she never becomes a mother. So I’m holding on to that last bit of hope.
