How I Met Your Father‘s Season 2 premiere marked the surprise return of Neil Patrick Harris’ Barney Stinson — and the cameo was merely an amuse-bouche, with NPH set to resurface a little ways down the road. In the meantime, TVLine is taking stock of the Hulu sequel series’ many nods, cameos and crossovers with the Mothership.
For the uninitiated: HIMYF picks up eight years after the events of the How I Met Your Mother finale, and focuses on a new friend group consisting of Sophie (Younger‘s Hilary Duff), Jesse (Veronica Mars‘ Chris Lowell), Valentina (grown-ish‘s Francia Raisa), Charlie (The Royals‘ Tom Ainsley), Ellen (Space Force‘s Tien Tran) and Sid (God Friended Me‘s Suraj Sharma). The story is told from the perspective of 58-year-old Sophie (played by Sex and the City‘s Kim Cattrall) — and unlike the original, the pilot establishes that our new protagonist has already met the dad, thereby confirming that the follow-up is operating under a slightly different framework than its predecessor.
Whether you’re already familiar with the spinoff or simply curious, the following guide provides a rundown of all the ways that HIMYF has paid homage to HIMYM and tied the two, largely standalone sitcoms together. Scroll through the following list to see if you’ve caught every tip of the hat to the OG series — and be sure to check back throughout the run of the show for inevitable additions.
