Walking out of the complex with one less member of their team, the atmosphere is surely not that great. Jeff is silent all the way showing that he's still grieving but tries to be strong, and Dinda also feels the same as she just experienced two losses on the same day.
Compared to Jeff, Dinda somewhat handled her grief better.
Pati can see it clearly that she's basically the same from how she's willing to go on their journey instead of grieving the entire day like any other people would if they just realized their parents' death.
But it might just be how she deals with grief, by making herself busy. Pati doesn't know.
Of course, contrary to the others Pati and Abby doesn't really get affected that much by Salsa's death. It's a pain since his walking backpack is dead, but he can replace Salsa with Abby. Just like right now, Abby is carrying the black bag that should be Salsa's job.
