On October 4, Elon Musk reversed himself and offered to honour his original proposal to buy Twitter for $44 billion - a deal he had spent the previous several months trying to wriggle out of. He made the latest offer just two weeks before a Twitter lawsuit aimed at forcing Musk to go through with the deal was scheduled to go to trial in Delaware Chancery Court. After receiving Musk's offer, Twitter said it intends to close the transaction.
The two parties now have to close the deal Friday. If they don't, the Delaware Chancery Court judge overseeing the case plans to reschedule the trial in November.
If the case has your head spinning, here's a quick guide to the major events in the saga featuring the billionaire Tesla CEO and the social platform.
January 31: Musk starts buying shares of Twitter in near-daily instalments, amassing a 5% stake in the company by mid-March.
March 26: Musk, who has tens of millions of Twitter followers and is active on the site, says he is giving "serious thought" to building an alternative to Twitter, questioning the platform's commitment to "free speech" and whether Twitter is undermining democracy. He also privately reaches out to Twitter board members including his friend and Twitter co-founder Jack Dorsey.

April 9: After exchanging pleasantries and bonding by text message over their love of engineering, a short-lived relationship between Agrawal and Musk sours after Musk publicly tweets "Is Twitter dying?" and gets a message from Agrawal calling the criticism unhelpful. Musk tersely responds: "This is a waste of time. Will make an offer to take Twitter private."
