I thought this episode opened with a bang after the Ted and Zoey first kiss. The banter at the bar followed by the ancient Rome skit were great. Barney as his invented St. Desperatius delivered the goods with the Roman numeral puns -- Her body is an X(10) followed by St. Valentine(Ted) saying, "High V(5)". Corny I know but Barney always pulls it off. We learn that Marshall has been in Minnesota grieving the loss of his father under the pretense that he is helping his mother. This is not the case and Lilly comes to see him. Not much comes from this segment. Then we get to the best part of the episode with Barney doing the "predator stalking" of the women on Desperation Day which leads to the pursuit of Nora. She is not easily influenced by his charms and Robin becomes the ultimate bro when she sets Nora and Barney up for an evening of his favorite hobby--laser tag.
Back to Ted and Zoey. Feels like too much, too fast, too soon.
