I get rid of outside distractions, listen to some sounds (wind, rain, a fireplace, whatever best fits the "mood" I'm aiming for) and write. Failing that, I write out a list of things that needs to happen in the scene. Like so.
--Protagonist talks to Bethany.
--Protagonist mentions something about how they need to leave the inn.
--Protagonist suggests leaving the inn.
--Protagonist leaves the inn.
If I order the actions I need to complete, it can make it easier to write it out. Even if it feels uninspired, it's at least coherent.
