Home and Away reveals new enemy for Colby Thorne in 11 new spoiler pictures

Amber is working as John's carer.

The pair had a rocky start, with John firing Amber after her first day. However, a shortage of other carers has led to Amber coming back for another try.

She wants to take John's ongoing rehabilitation to the next level, feeling that his progress will be slower if he only does exercises at home.

He's starting to warm to the Summer Bay newcomer, after initially being put off by her brash attitude.

She already shares a history with Colby, Dean and Willow, as they all grew up together in the Mangrove River area.

Her presence in Summer Bay is sure to shake things up for her old friends.

Earlier on, Amber punched Colby when they came face-to-face at the beach.

They share a troubled history.

Amber blames Colby for the death of her brother a few years ago, believing that he could have saved him. She makes it clear that she'll never forgive Colby for fleeing from the scene and failing to help.
