Impala was about to respond, but Pinkie beat her to it and at a very fast pace that Impala just barely understood. "Hey Twilight, I found this new mare walking funny around town and she said that she needed a place to stay, so I first thought that I would let her stay at my place so that I could help a new friend and so that we can lots of fun, but when she mentioned about needing to find a library I thought of the most super duper greatest place for her to stay, so can you let my new friend stay at your place for a while? I know your place is very big and only you and Starlight and Spike live here I thought maybe you could use some more company here and Impala here is the perfect fit so can she stay with you?!"
