SPOILER MAYBE ? never read the books...

at the bus station when Katie was sitting there waiting for her bus, was that her birth mother (forget her name) but Sherri Springfield buying a ticket to get on the bus as well? The woman looked so much like her birth mother - I know the last we see her she was already laying in a hospital bed in New York; so I was confused if that was her at the bus station - I swear it looked like Sherri Springfield.
Sorry for the dumb questions but it really confused me bc of how much the lady looked like her birth mother; then they end up on the same bus going to New York... thanks for any information you can give me, I appreciate it, sorry for being a dimwit as well (lol).
