Ms. Angel is basically thanking Rider for safely escorting Mori. When she knew that Mori was missing from the shelter, she thought he followed Rodina, his friend who left with her mom, so she tried to track Mori in the direction of Rodina's house. She didn't know that Mori would actually go to her instead. She was looking in the wrong direction. That's about it.
So basically in ch 13, ms. Angel said that "mori's friend at the shelter" (rodina) left so she tried to track him in the direction of her home. The translations have been wonky with the pronouns lately that I had to look at the raws.
