Iago invites several rowdy soldiers up to party with them and, of course, Cassio is eventually persuaded to drink more than he can handle. Cassio does, in fact, become violent and ensues a fight against Roderigo, eventually even wounding Montano. Othello hears the ruckus of the fighting and comes to break it up. Iago tries to make Cassio look good in a move of reverse psychology but, in the end, Othello tells Cassio to leave his service. Iago's plan is swiftly put into motion by his sneaky ulterior motives and plan to get rid of Cassio. Iago plays to Cassio's weakness and by seeming very friendly and just up for a good time, subtely gets him drunk and agitated, leading to his demise.
