Bex and I walked up the stairs. Then Liz joined our steps, then Macey. I don't know what's going to happen next semester. I don't know if Josh will ever talk to me again. I don't know what he'll remember, or what we'll face in CoveOps, or even what Mr. Smith will look like come September. But I know who will be beside me, and as every good spy knows—sometimes that's enough.
