Apologies for premature exhortation, as there was no reappearance of Robin Sparkles on tonight’s How I Met Your Mother. The television stars are scheduled to align for “Sandcastles In The Sand” next Monday, 4/21.

As a huge HIMYM fan, I admit “The Chain of Screaming” wasn’t one of the comedy’s best episodes. But if you were a first-time tuner, please give it a second shot next week. Otherwise, Mother might not live for a fourth season (and I’ll totally blame you).
