"Feels Like Rain" is one of those wait and see episodes. There are no large plot developments, but it's not entirely filler. There are plenty of small developments, but none that warrant extra attention. Aside from Sofia's plot, which is beginning to bother me, the episode is as solid as the rest, if unremarkable.
One of the bigger themes in the episode is musical development. There's Antoine trying to teach the students that music isn't about notes on sheet while maintaining his band, Annie trying to figure out what makes a good song good, and Davis starting a band that has a message. Although the payoffs will be further down the line, everyone--except Sonny, who once again finds himself out of a job after being late too many times--is moving in the right direction.
Score: 8.7/10
