IPOD TOUCH RECEIVING iPHONE'S MESSAGES

My sister gave me her iPod touch, so I restored it & updated the iOS. When I updated it, it downloaded the messages app (the one found on iPhones) but didn't give me the option to delete it.
I figured no big deal and just ignored it. But then I got a little notification and I'm receiving my mom's messages! Everything sent to her is coming to both her phone and my iPod. It doesn't give me the option to send back though.
What can I do to fix this?
