“Neighbours” posted a sneak peek of Tuesday’s episode on its Facebook page. In the clip, Belinda is seen helping Ari breathe properly, while Charlie is texting someone, looking for help. However, Ari catches Charlie and throws away his phone. Belinda rushes to cover Charlie and fear registers on her face when Ari brings out a knife.

Digital Spy reports that Belinda gets out of the safe house for a bit, finding being holed up with Steph a bit awkward. She runs into Charlie, who’s playing with his drone. Ari finds the two, and professes his love for Belinda. It’s not long before Ari turns into a dangerous man, threatening Belinda and Charlie’s lives. Fortunately, Mark arrives in time, but he gets stabbed in the process of trying to catch Ari.

Meanwhile, Amy’s confession pushes her to become closer with Jack. Paige, on the other hand, faces a dangerous opponent – one whose sparring partner ended up being hospitalised. Aaron tries to withdraw Paige from the match, but because he’s bound by the contract, he must still pay the boxer’s fee of $12,000.

“Neighbours” recap

On Monday, Brad was floored after learning from Susan that Piper filed an official complaint against Elly for unfair treatment. When Susan confronted Elly, she denied calling Piper any names. Elly started to get nervous, especially when Susan said that she has no choice but to investigate on the matter. Later, Elly asked Ned to look through Piper’s phone for a vlog, proving that the schoolgirl has a vendetta against her teacher. Despite his hesitations, Ned did it for his girlfriend, after Elly said she might lose her job and may be forced to move away.

After a thorough investigation and careful deliberation, Susan deemed that the grade Elly gave to Piper was fair. Piper was flabbergasted, but even more when Susan mentioned about the vlog. Piper was surprised that Susan found it – she deleted it right away. Susan said the source is irrelevant, but it proved that Piper resented her teacher. Elly gloated about her victory and acted like she’s taking the high road. Later, Piper ranted to Ned about Susan’s decision and he felt utterly guilty for helping Elly.

Amy went to the confessional to pour her heart out about her loneliness and insecurities, while Mark was listening in. He didn’t mean to eavesdrop on Amy, but he planted the bug to search for more leads about Steph’s stalker. Later, Amy realised that Mark knew she was in the confessional. Jack and Amy discovered the bug that Mark planted.

Meanwhile, Mark gathered a list of people the police should look into regarding Steph’s case. The list included Paul and Belinda. Later, Belinda nearly gave Steph a heart attack when she suddenly showed up. Once she caught her breath, Steph was even more stunned when Belinda said she knows who’s responsible for everything that’s been happening. Belinda said it’s about her, not Steph.

Later, Mark arrived to talk to Belinda, who revealed that the stalker is Marion Philcox, a former patient who’s in love with her. He was recently released and Belinda believed that the stalker asked around about her and traced her back to Steph. Belinda also said that Marion is a reptile hunter. When Mark heard that the stalker is Ari Philcox, the snake catcher, he immediately rushed to find the culprit. However, when Mark went back to the wildlife sanctuary, he found that Ari already left with his snakes. Mark feared for Steph and Belinda’s lives. He told them to pack some stuff, then took them to a safehouse while Mark tracked Ari down.
