In Season 4, Brock was intentionally poisoned and nearly died. A distraught Jesse was convinced it was a result of the ricin cigarette Walter White created but the latter convinced him Gus Fring was behind it. As it turns out, Walter had indeed poisoned Brock, using the berries of a plant called Lily of the Valley, in an attempt to turn Jesse against Gus. (Jesse would eventually learn the truth.)
Aaron Paul discusses El Camino’s big cameos below:Brock eventually recovered but he and his mother remained in danger due to Jesse’s ties to the meth trade. After Jesse was kidnapped by Jack Welker’s Neo-Nazis, he watched helplessly as Jack’s nephew Todd executed Andrea before his eyes. Brock ended up being raised by his grandmother.
Unlike many of the other characters on Breaking Bad, Jesse actually had a conscience and was guilt-ridden over what had befallen young Brock and his family. Actor Aaron Paul told IGN at the press junket for El Camino that he knew what Jesse’s letter to Brock said, describing it as “a beautifully honest, heart-wrenching sort of love letter to Andrea and to Brock. A confession in many ways.”
Watch the Breaking Bad cast reveal their favorite Jesse moments:Paul also revealed that Jesse’s letter was the “very first thing that Vince [Gilligan] wrote when he wrote the script. It was originally in the script, but then it was cut out before we started rolling.”
The actor added the letter “was very hard to read. And hopefully, knock on wood, Vince will allow me to release it to the world one day. I fought very hard to have it still in this film, but he wanted to leave it to mystery.”
