Episode 5 of Unstable unfolds with a jarring turn as Ellis inadvertently collides with the identical twin, Chaz, with his vehicle. Matters escalate swiftly as the twins accuse Ellis of orchestrating a sinister plot to murder Chaz on his very birthday.
Determined to rectify the misunderstanding, Ellis and Anna concoct a story, claiming they intended to surprise the twins with a birthday gift but had forgotten it at home, promising to deliver it the following day.
The next morning, Anna and Ellis find themselves embroiled in a frantic quest for the perfect gift to avert Ellis's impending prison sentence. Amidst their deliberations, Jackson drops a bombshell: the lab crew is taking an early respite and heading to the local watering hole that evening. Coincidentally, Ruby and Luna are also discussing their plans to frequent the same bar, with Ruby confiding in Luna about her complicated relationship with Jackson.
Armed with a two-seater bicycle as a gift, Ellis and Anna venture to the twins' abode, hoping to turn the tide with their surprise. However, their efforts fall flat as the twins reveal they've already received the same bike from multiple sources, leaving them unimpressed. In a bid to salvage the situation, Anna and Ellis impulsively invite the twins to join them at the bar, spinning a tale of a grand birthday bash in the making.
As the night unfolds, Ruby, Jackson, Luna, and Malcolm converge at the bustling bar. Ruby and Jackson seize the opportunity for some much-needed one-on-one time, slipping away for a drink. Meanwhile, Luna's persuasive nature prompts Malcolm to engage with the HR representative who's just arrived, albeit reluctantly at first.
The chemistry between Ruby and Jackson seems palpable, but their idyllic moment is disrupted when Ruby's former flame strolls in, drawing her attention away from Jackson and stirring up emotions. Disheartened, Jackson retreats to Luna's table, initiating a conversation that serves as a welcome distraction from his own troubled thoughts.
As Ruby prepares to depart with Cooper, a subtle shift in the atmosphere unsettles Jackson. Just then, Ellis and Anna arrive at the bar, accompanied by the twins, weaving a web of birthday festivities that ensnares the entire lab crew in their mischievous ruse. The twins, being somewhat oblivious, play along effortlessly, making the charade a success.
In the aftermath of Ruby's apparent departure, Luna and Jackson forge an unexpected connection, fueled perhaps by Luna's subtle evasion of her boyfriend waiting at home. Their moment is briefly interrupted by Ruby's sudden reappearance, informing Jackson of her true whereabouts—leaving Cooper behind in a taxi.
Luna, sensing the shift, gracefully offers to step aside, allowing Ruby and Jackson their privacy as they exit. But as the night progresses, Luna sheds her inhibitions, taking to the dance floor with a renewed vigor once Jackson has departed. The others, captivated by her transformation, soon join her, turning the evening into a vibrant celebration of life's unexpected twists and turns.
