[When Evan comes back to the apartment, Louis' things are gone. The change isn't drastic, since it wasn't ever really meant to be a permanent stay, but marked - the clothes he brought over, the toothbrush, gone. The bed is made. It's like he was never there. Also, any items with alcohol, even a small amount, are gone, though that was done before he went to the airport.
There's a folded note on the kitchen counter. It's a little wrinkled, like it's been crunched and smoothed out again. It's made a trip to the waste basket, then been thought better of and put back with care, weighted under a water glass. On it is Louis' phone number, which Evan already has, but it's a message - call him. Under that:]
If you need anything.
[It's stiff and formal, and he hates it, but he doesn't want to intrude, and he doesn't want to press too hard, so that's all that's left behind.]
