Star vs. The Forces of Evil Season 4 Episode 17 - Sad Teen Hotline/Jannanigans >Star, Marco and Tom go see Janna as she was the only one to arrive on Mewni without a portal. The ever aloof Janna claims that she honestly does not remember how she ended up there, but that it was a "normal Thursday". She tries to recreate the events of the day during which Tom suggests to Marco that he is okay with him going out with Star again despite the Blood Curse being lifted. Janna, for the first time ever, displays actual stress of the constant pressure the group is putting on her. Feeling bad, they head to Britta's Tacos where Janna suddenly remembers what she did. She broke into the restaurant's back door and found a cave where a large mural of Mewni origin lies. They find a well that Star remembers she came out of with Moon and realize that this is their way into Mewni.
