But he also knew that the risk of Brock dying was real, especially if he was not diagnosed in time. Moreover, it is Jesse who immediately directs the doctors towards a poisoning. Perhaps without this, the diagnosis would have been too late.
Later on, Walt himself admitted to Jesse that he poisoned Brock with a Lily of the Valley plant just to keep Jesse on his side in order for them to orchestrate the death of Gus Fring, but by that point, their relationship was already in shambles.
In Hazard Pay, Walt sees Brock at Jesse's house, but Brock doesn't seem to show any kind of recognition of Walt. He acts like a normal shy kid, being quiet around a stranger. Walt does give him a long stare at one point, like he's thinking, "So this is the kid I had poisoned."
As a loving father of a son, Walt without doubt hates himself for involving/using kid in his "war". But that's just it, he doesn't feel sorry for doing it at all, mostly because from his perspective his confidence/ego (about poison dosage) is so high that he doesn't feel like he put that kids life in danger at all.
In the season 5 episode Confessions Jesse realises that Saul and Huell took his ricin cigerette on the orders of Walt (Jesse finds this out by threatening them with a gun) which causes him to also realise that Walter was behind the whole false story of Gus poisoning Brock when it had been him all along.
Did Jesse forgive and still love Walt at the end? Nope. Walt absolutely destroyed Jesse's life. He did unforgivable things to Jesse, such as letting his girlfriend die and poisoning his other girlfriend's son just to manipulate Jesse.
Many thoughts of grief may have flooded Walt's mind after Hank was killed in Breaking Bad, but the reason why Walt tells Jesse the truth about Jane's death is indicative of his true nature. Walt's evolution to becoming Heisenberg was created out of a series of events of desperation and tragedy.
Off camera, Walt crushes up some of the poison from the Lily of the Valley plant and injects it into a juice box. Also off camera, Walt delivers the juice box to Brock's school. (Having seen Brock the day before at Jesse and Andrea's place.)
It belonged to a man scared of Gus Fring, scared of Tuco Salamanca, scared of chemotherapy, scared of cholesterol. So, after taking a long look at his porkpie, he sells the car to the mechanic for fifty bucks — a dollar for each year of his previous life. “Dad, are you crazy?” Walter Jr.
Throughout the five seasons of Breaking Bad, Walt caused the death of almost 300 people, directly or indirectly. As the character descended into wickedness, Walt didn't necessarily seem to fall under the label of a psychotic murderer.
Walter used Lily of the Valley instead of ricin because it has similar attributes to ricin without actually BEING ricin. If it was actually ricin in Brock's system chances are Jesse would have been taken by the FBI.
The reason Brock is odd around Walt is that he's only seen him twice and doesn't know him at all. I remember that when the first time Brock has seen Jesse, he was very quiet around him too.
Jesse, however, was left with $5 million that Walt gave him out of guilt.
In Breaking Bad Season 4, Gus was aware that something might be wrong with his car because Walter had told him that he would bomb the car. This was a result of Jesse's loose lips.
No. From the moment Walt had him dragged out from under that car in the desert, Jesse never forgave his former partner. From that moment on, Jesse felt nothing but hatred and resentment towards him.
Walt was just unable to believe his situation, how things stacked up against him. First being diagnosed with cancer and other series of events, then with his last bit of stash gone, he just burst in laughter feeling the agony.
The $80 million profit Walt turned by selling meth for just one year is a very realistic sum for a true-life drug kingpin.
Around this time, Walter dated his lab assistant, Gretchen Schwartz (Jessica Hecht). He left both Gretchen and Gray Matter Technologies, selling his financial interest in the company for $5,000. Gretchen and Elliott later married and made a fortune, much of it from Walter's research.
Using his mastery of chemistry to his advantage, Walter developed a form of crystal meth that was the purest the world had ever seen. The Blue Sky drug took off and started selling like hot cakes. Before they knew it, Walter White and Jesse Pinkman had made a hell of a lot of money as well as even more enemies.
It's revealed in Season 5 that Ted ended up hospitalized with severe neck trauma. He has to keep his head in a huge protective brace and his head was completely shaved.
Jesse didn't knew if Walt killed Mike or not, but he had suspicious because of one reason: Mike was totally against the idea of killing his guys in prison, after Mike's "depart", Walt killed them anyway.
Walt had a host of reasons to get rid of Lydia - she was a threat to his family, which he was no longer able to protect (and she's already shown she has no qualms getting rid of people, regardless of the size of the threat); she was both the distributer of the blue meth and a potential supplier of methylamine; she was ...
As Walt either wouldn't or couldn't do anything to save Jane, he decided not to wake Jesse up, knowing that her death would help him gain control over Jesse as a result, and possibly saving Jesse from the same fate and to protect his own criminal secrets. Walt watching Jane die.
As the Whites leave, Walt gives his in-laws a DVD of his "confession." Playing it at home, Hank and Marie discover they are being blackmailed. Walt's "confession" states that Hank masterminded the Heisenberg empire and forced Walt to cook meth for him.
The calculated malice of the whole thing is made crystal-clear by the fact that, as Jane begins to choke on her vomit due to an overdose, Walter's instinct is to turn her on her side to save her, but then he stops himself because the idea of her living means more trouble for him.
