Lease ends in two months

So my wife’s Toyota Corolla lease ends soon. She got it before we were married. I already had two paid off cars coming into the marriage. So we don’t plan on buying it out or leasing a new one. She’s under the mileage agreement.

What are the gotchas I need to look out for and how to combat them. Hoping it’s as simple as dropping off the car and keys and be done with it. Any information is greatly appreciated.
