Loki had taken a look at the Heart earlier on, then decided to go back and look up something in his library. He hadn't expected to see another person when he tessaracted right back to the Heart. Dirty trench coat. Dirtying the air with his addiction. Yep, he knew that person.
"I would summarise it as 'it did not spark joy'", Loki said, a half-smirk on his face. His niece had gotten sucked into a show by a Mrs. Marie Kondo. Suzume had tried to summarise it three times to him. Three times he had not understood the appeal of watching someone organise their things. That hadn't stopped his daughter from jumping on the band wagon. Now, he had quotes around the house. Loki's take away was that 'sparking joy' was obviously a popular Midgardian saying so why not quote it at the next Midgardian?
