Re:ZERO - Starting Break Time From Zero 2: Otto's Diary 3 - S0.E28

After encountering Garfiel and escorted to the Sanctuary, he finds himself stranded in the middle of nowhere. He suddenly noticed that Garfiel was right next to him. He tells Otto to go to Roswaal, but he was told by Ram to not visit him. He then asks him how did he know Frederica and Garf are related. Otto didn't understand what he meant and he thought that Subaru told him that and he insists that it was due to their sharp teeth, but Garfiel didn't get it. The episode ends with them trying to find the saying is either "The rushing ladybug folds leaves" or "The rushing ladybug blows up".
