I love the car scene in PHF before Sheila kicks Fugo out, both in terms of the development of their relationship but also as a highlight of the tragedy that comes with Sheila's character, because it's the first proper time we see someone witness and acknowledge her pain and trauma, as well as her being so vulnerable. Prior to this, Sheila's this sort of reliable, highly capable person who, although her having issues is noticed by people, isn't really reached out to, both because she wouldn't accept help if it didn't come from her own initiative most likely and also because everyone else is preoccupied with the trauma of canon events.
Fugo's no exceptions to this, being extremely worried about Himself and the FutureTM in that scene until Sheila starts opening up, but seeing Sheila be vulnerable and unravel the trauma that's been hiding in plain sight that he and everyone else could afford to not pay that much mind to – since Sheila has been functional and reliable as always, creating this illusion of Being Okay on her own – made him recognize that he's not the only one suffering and struggling, and him locking in to come after her and commit to killing Volpe, from a purely from a characterization perspective, shows a degree of selflessness, compassion and empathy that I very much connect with Fugo (because of the anime) but that's also missing in his PHF characterization but that's a post for another day—
Point is, I adore that scene, because I feel like it's an in-universe escalation of what a lot of readers are also guilty of, which is ignoring Sheila's trauma and pain. Fugo, as well as the readers, can no longer ignore it, and it helps Fugo find a direction to move towards – help someone in their suffering by trying to prevent it from getting greater. Wonderful.
