Can my friend and I move seats so we can sit together ?

Hey guys my friend and I messed up when buying tickets and since we were buying our own tickets we selected buy one ticket thinking we would be able to purchase tickets next to each other but we ended up not being able to so I’m sitting in the same section as her (section 112) but in different rows, I’m in row 17 and she’s in row 15. The tickets aren’t refundable and they are for the January 7th game and I was wondering if once we are in the arena can we possibly swap seats or move elsewhere where we can sit together or do we just accept we will be sitting separately?
