Mathew Newfield was Abigail's boyfriend before the crash of Oceanic Flight 815. During the flight, he and Abbie split up.
After the crash, Mathew was separated from the rest of the Oceanic passengers and he spent 51 days alone until he was finally found, with Olivia.
Before the crashEdit
Oceanic Flight 815Edit
Whilst finding their seats on the plane, Abigail saw Mathew "checking out" other passengers of the plane, so she hit him to make him stop. ("Flying the Nest, Part 3")
When Josh and Claire dropped their bags and they bent over to pick them up, Abigail thought he was "checking" Claire out as she bent over. She finally had enough and broke up with him. He then spent the rest of his flight alone and he later presumably died in the crash. ("Flying the Nest, Part 2")
After the crashEdit
Days 47-51 (Season 2)Edit
When Darien followed Melissa into the jungle to protect her, they both saw a shadowed figure running in the distance, this was Mathew. ("The Whole Shebang")
Four days later, Mathew was carrying Olivia through the jungle when he was found by Josh, James, William and Darien. ("Moments in the Woods")
