The Celebration Begins
Ever wondered how quickly a night can go from celebration to disaster? That's exactly what happens when Iago puts his sinister plan into motion during the victory festivities.
Othello leaves Cassio in charge of the guard duty, trusting him to keep things under control whilst he and Desdemona finally consummate their marriage. It's worth noting that they've waited until marriage - quite different from the crude assumptions other characters have been making about them.
The moment Othello leaves, Iago begins his psychological warfare. He subtly suggests that Desdemona might be a seductress hiding behind a modest exterior, trying to plant seeds of inappropriate desire in Cassio's mind. Cassio, being honourable, sees only her genuine modesty.
Key Point: Notice how both Othello and Cassio completely misjudge Iago's character - this shows just how skilled he is at appearance versus reality deception.
When Iago pressures Cassio to drink, Cassio wisely refuses, knowing he can't handle alcohol. But Iago persists, and eventually convinces him to let the revellers in. This is Iago moving from verbal manipulation to more direct methods - getting people drunk to control them.
