Othello 3.1-3.3

"Yet I beseech you,\If you think fit, or that it may be done,\Give me advantage of some
brief discourse\With Desdemona alone." (3.2.48-51)

This is is large role in Othello's jealousy. When Cassio starts to hang around Desdemona so much, begging her to get Othello to forgive him, Othello then starts to conjure up a relationship that doesn't exist.
