A murder and the discovery of a body in a park lead Nick (David Giuntoli) and Hank (Russell Hornsby) to an insect Wesen that emerges from the Earth every seven years for 24 hours.
Back in the loft, Adalind (Claire Coffee), thanks to Diana (Hannah R. Lloyd), finds an injured Eve (Bitsie Tulloch) in the tunnels, where she has painted the wooden shard's cloth symbols in the walls during a trance.
Meanwhile, Monroe (Silas Weir Mitchell) and Rosalee (Bree Turner) learn they're expecting triplets and Renard (Sasha Roiz) tries to discover if Meisner (Damien Puckler) is a ghost or an hallucination.
If nothing else though, it at least fits into the whole of 'The Seven Year Itch,' an episode that has some intermittently interesting moments but for the most part misses the mark on what it's trying to achieve.
"[4] Kathleen Wiedel from TV Fanatic, gave a 3 star rating out of 5, stating: "It's probably fair to say that there is a significant portion of the fan base that finds Wesen-of-the-Week stories... well, boring.
"[7] Christine Horton of Den of Geek wrote, "As much as this episode doesn't do much to progress many of the recent storylines, it delivers what fans generally like about the show: the hunting of malevolent mythical creatures, acerbic one-liners and a little Monrosalee-shaped fluff.
