While Zack (in the body of Mr Munk) is talking to Ms Arlington about Zack, Cam and Spence's planned absence from her class, she is writing on the chalkboard. The scene cuts back and forth from wide shots to closeups showing Ms Arlington's reactions. In closeups she has written, "Evaporation is the gradua" - the word is unfinished - while in long shots she has written more, "Evaporation is the gradual process". As they talk, she adds the words ". . . in which", then a closeup again shows most of the words missing.
