Musk started buying stock in the micro-messaging service almost daily in January.

By the spring, Musk had amassed a 9.2% share in the micro-messaging service. The board was going to get Musk on it.

As part of the lawsuit against Musk, messages were released between the two.

I'm happy to be connected directly with you. A message was sent to Musk on March 27.

The three men met for a meal near San Jose.

Musk sent a message after dinner.

It wasMemorable for multiple reasons. I really liked it.

After a short time, the relationship soured.

Musk said on April 9 that some of the most followed accounts on the platform rarely post. He asked if the social networking site was dying.

The man didn't like the thing that was said.

It's Musk's responsibility to tell him that it's not helping him makeTwitter better in the current context.

This week, what did you do? Less than two minutes later, Musk responded in a series of texts. I am not going to join the board. This is not a good idea. Will make an offer to take the social networking site private.

Is it possible to talk? The reply was given by Agrawal. According to the message logs published as part of the lawsuit, Musk didn't reply to him, but he did reply to a message from Taylor and tell him that he needed "drastic action."
