Before the crashEdit
Oceanic Flight 815Edit
Minutes before the crash of Oceanic Flight 815, Josh and Anya over heard and saw him talking and flirting with Cindy Chandler. Anya commented on it mockingly. A few seconds later, as Josh was walking down the plane aisle, Josh saw Jack standing up, so he changed direction and moved out of the way. ("A New Beginning, Part 1")
On the IslandEdit
Days 2-6 (Season 1)Edit
The day after the crash, during the rain storm as Alex, Charlotte and Josh were all searching for food, Alex saw Jack running away from the cockpit, immediately after the pilot was ripped from it. ("A New Beginning, Part 1")
A few days later, while some of the survivors were out searching for food, Josh heard Jack shouting 'Where are you?!', however, Josh didn't know it was Jack shouting. ("Man in Black")
