Aubrey Plaza Opens Up About Grief Following Husband Jeff Baena's Death During his podcast appearance, Johnson admitted that he gave up hiking for a while after Baena's death, as it was a beloved hobby for the pair and reminded Johnson of his friend.

"It happened when my dad died too," he explained. "My brother was like, 'You gotta speak.' And I was like, 'I don't.' ... I was like, 'Who am I f***king speaking for?' His AA buddies, 80-year-old Jewish guys, cousins on my dad's side I didn't grow up with? I don't need to cry in front of strangers." Johnson said he eventually realized that he was doing the eulogy for his late father. In the same vein, Baena's eulogy was for Baena. Johnson also said he wanted to "challenge" Baena in his eulogy in the hopes that Baena's spirit would appear at the funeral.

"I thought something was going to shift, so that I could say,' I'm sorry I didn't see it.' 'Cause the real nightmare of suicide is you think you got a good read on people and you missed it," he continued. Jake Johnson Had an Instant Connection With Jeff Baena Describing the type of friendship he had with Baena, Johnson said that they often got into "debates" because of their similarly stubborn personalities. "Our hangs, similar to you and me, we would get on a subject, and then sometimes it would turn into a slight debate, even very similar," Johnson told Shepard. "So Jeff and I had a ton of topics. And when he killed himself, all the debates stopped. And I was like, 'That's not fair, man, because we haven't finished.'" Johnson also said he and Baena had an "instant" connection when they first met. "When I met Jeff, we connected right away and he said, 'We're going to be old men together. And I was like, I know that's true. We are going to be playing Bocce Ball and I'm going to be arguing with this f***ing old man," he added.

Jake Johnson Opens Up About His Regrets With Jeff Baena Johnson admitted that Baena's death has weighed heavily on him because he has felt like he could have done more to help him. "We were supposed to hike," Johnson said, revealing that he turned down a hike with Baena just before his death due to a scheduling issue. "But here is where I look back where I go, like, because he had told our other friend Miguel, when things were going dark for him, Miguel said, 'Talk to Jake, Jake loves you.' And he goes, 'Jake's really busy with his kids and his work. I don't want to bother him.'" Johnson continued. "And now he's dead. ... I do think if we went on that hike that day, in my heart of hearts, I know he'd be alive." However, Johnson emphasized that his thoughts and feelings do not reflect every situation. "To anybody who's listening, who's lost somebody, I'm not talking about you. So I'm not saying you did anything wrong," he told listeners. "I don't know your story. I just know Jeff."
