Tinker, being Tinker, ignores everything that doesn’t connect to what she’s focused on at that moment. Yes, she knows that the Harbingers have showed up; she doesn’t think about them in the last chapter. Yes, she knows Jewel Tear was rescued by Tommy and is living with Oilcan; not a word about the battered female. She also knows that something happened involving the trains at Station Square. She doesn’t think about that either. (To be fair, she didn’t know that Oktoberfest was being held there and that loads of humans were in danger. She will freak once someone finally connects the two for her.)
