Scott Knowles was given the CTO job over Tyrell. Tyrell was plotting against him and planned to sleep with his wife. Joanna (Tyrell's wife) was pushing for him to do this to push Scott's focus away from the CTO job and allow Tyrell to get the job instead. Unfortunately, that backfired and Scott got the job.
The problem is, Scott's wife actually moved forward with sleeping with Tyrell. In the process, he ended up strangling her to death on the roof of the Ecorp building during Scott's party celebrating his promotion. Scott suspected Tyrell of the murder. Well, he all but knew that he did it.
Throughout this season, Joanna has been receiving phone calls and gifts. The calls were from someone who never spoke but simply breathed into the phone. Joanna thought/hoped that it was Tyrell who disappeared after the 5/9 hack.
3 episodes ago, Joanna got Elliot to track down the number from where the calls were coming from. He gave that location to Joanna's henchman. The location was Scott Knowles home as we come to find out in the finale.
When Joanna goes to confront him, we find out that his wife was pregnant when Tyrell killed her. He was awarded the CTO job but lost everything else in the process. Knowing that Tyrell was gone, he used the phone calls and gifts as a way to give her "hope" that Tyrell was still out there so that he could eventually use it to crush her spirit if he turned up dead. It was a revenge ploy to get back at her for what Tyrell did to his wife (above already refusing her Tyrell's severance package money earlier in the season).
The final scene with her new boyfriend is Joanna manipulating him to tell the police that it was Scott who looked suspicious for killing his own wife, etc. To get back at him for the beating.
Holy shit you're like a Mr Robot angel.. that is awesome.. I can't believe I forgot that entire plot from last season and honestly was lost all season wrt Tyrell wife.. geez I need to rewatch both seasons now
Scott finds out he's becoming the next CTO.
Scott finds out his wife, Sharon, is pregnant. Happiest day of his life.
Scott and Sharon have Tyrell and Joanna over for dinner after the CTO position is publicly announced. Tyrell seduces Sharon and literally opens her legs for him. Nothing else happens.
Night of the celebration for Scott, Tyrell and Sharon go up to the roof for sex. Tyrell loses it and strangles her to death.
Police find the body, Tyrell becomes the lead suspect. Tyrell gets fired from E-Corp.
Joanna has their child.
5/9 happens, Tyrell disappears.
Joanna is running out of funds. Needs money so she goes to Scott to get Tyrell's severance package from E-Corp. Scott tells her to basically fuck off.
Joanna starts receiving strange gifts. Gifts that that would most likely be from Tyrell, giving her hope. One of those gifts is a cell phone.
Joanna approaches Elliot thinking he's behind Tyrell's disappearance. He doesn't know, but helps her trace the phone calls from the phone.
It's from Scott's home. Scott was behind the gifts. Joanna finds out that Sharon was pregnant and insults them to provoke Scott to attack her. She uses the attack to convince her boyfriend to lie to the cops about the night Sharon died. She now has everything to get Scott fired, out of the picture, and finally get the severance package.
And thank you also!
I need to stop multitasking while watching this show..
