Connecting the dots between Nina’s bizarrely futuristic blueprints they see her looking at and the fact that Bunny apparently “had to go,” Nina and Jared are looking awfully suspicious, which causes Charles to have an anxiety nosebleed.

“Hey, you still get a bloody nose!” Zoe Colletti’s Lucy says to Charles in the tunnel before he wipes the blood away with a tissue.

Season 2 episodes of Only Murders in the Building release on Tuesdays on Hulu.
