Answer 1

EPISODE 4296 - Drew is stunned as he tries to come to terms with the fact that Peter’s standing before him. Peter moves to him, wanting to explain, but Drew cowers back wanting to know what the hell’s going on? Peter explains the story – how he brought down the prominent mafia-type family, the Gillen’s in the 90’s for their mass drug imports. The entire family was jailed and soon after, Dennis Gillen’s wife was murdered in her cell. Dennis vowed to hunt Peter down and kill him in revenge. Peter received word just before Zoe’s recent rampage, that Dennis had been freed from prison. The CID wanted to put him into hiding for safety, but after the hell year of tracking Zoe, he wanted a normal life back again. The Witness Protection people had other ideas and had been watching Peter for some time. When the explosion happened at the wedding, they saw this as the perfect opportunity to ‘remove’ Peter from society. They quickly hatched a plan, leading everyone to believe that Peter was dead, by giving him a drug which induced a very deep coma like state and in turn lead the hospital machines to produce false readings. When news of Jack’s need for a liver came to light, the Witness Protection team enlisted the help of Dr Green to make all believe that Jack was receiving Peter’s liver. Dr Green then provided them with medicines to aid Peter’s recovery while he was residing in the safe house. The first Peter knew of any of these plans was when he woke up two days later. He was outraged to learn of all that happened against his will, but it was too late to do anything about it – Peter Baker was dead. Peter then confirms that the thugs were targeting Drew to try and get Peter out of hiding as they had discovered that he was still alive, but Peter didn’t learn of their threats to his son until much later on, which is why he came back. They have to move quickly now – Dennis Gillen is still after him and wants him dead. The only way to protect Drew is to turn himself in to Gillen. Drew refuses to let Peter turn himself over to be killed – there has to be another way! Peter forces Drew out to the car, insisting that this is the only way, both on the verge of tears. Then a car pulls up – it’s Frank, the thugs and Dennis Gillen! Peter begs that they let Drew go – Dennis doesn’t care, it’s Peter he wants. Drew refuses to flee, but Peter forces him to go, watching sadly as his son runs into the bushland. Drew’s legs buckle beneath him as he hears a gunshot ring out – he collapses to the ground sobbing.

Answer 2

Peter (somehow) faked his death and has been in hiding.

The bad guys are after Peter but couldn't find him so they threatened Drew, knowing that Peter would protect him.
