Whittaker and Robby are in love
It might be wishful thinking, but many fans have noted a strong connection between Dr Michael “Robby” Robinavitch (Noah Wyle) and Dr Dennis “Huckleberry” Whitaker (Gerran Howell). This pairing has inspired the hashtag #Hucklerobby, reflecting the perception of a mentor-and-mentee relationship characterized as a “troubled moral saviour” and “damsel in distress.” Their bond, often forged through shared trauma, is a frequent subject of fan art and discussion.
“I get sent a lot of fan art of Gerran and me,” says Wyle. “Sometimes we’re cowboys. Sometimes we’re camping together or taking a nap in a hammock.”
“I get shown it,” adds Howell. “Sometimes against my will.”

AI will cause a patient’s death
Dr Baran Al-Hashimi (Sepideh Moafi), a recent addition to the team, is known for her frequent use of AI-driven medical tools. She has acknowledged that generative AI is only 98% accurate, raising concerns about its reliability in critical medical situations. This has led to speculation that a patient’s death might result from a misdiagnosis or incorrect medication prescribed by AI, serving as a cautionary tale about the risks of emerging technology in healthcare. Given the creative team's apparent skepticism towards AI, this theory resonates within the show's narrative.
Dr Abbot doesn’t exist
Dr Jack Abbot (Shawn Hatosy), Robby’s overnight counterpart and an amputee with a military background, shares a complex relationship with Robby, including moments where they talk each other down from the hospital roof after difficult shifts. Some fans theorize that Abbot might be a hallucination or an alter ego of Robby, similar to the concept in Fight Club. However, Abbot’s interactions with other characters make this unlikely.
Dr Robby will adopt the abandoned baby
Throughout season two, an unidentified infant, referred to as “Baby Jane Doe,” has been undergoing pediatric tests after being found abandoned in the hospital. This has sparked speculation that a staff member might be the mother. Charge nurse Dana Evans (Katherine LaNasa) has told Robby that the baby needs fostering, leading to conjecture that Robby might adopt her. However, Noah Wyle has dispelled this theory.
“I think Robby hits the road and thinks to himself, ‘Boy, it would have been nice to be in a better place where I could actually have taken that kid. Maybe one day.’”

Dr Santos will die
Some fans suggest that the character facing crisis may be Dr Trinity Santos (Isa Briones), who is struggling with her residency and fearful of repeating her second year. Her nemesis, Dr Langdon, has returned after a rehab stint, and most colleagues seem to support him despite her reporting him for drug theft. Additionally, her complicated relationship with surgeon Dr Yolanda Garcia (Alexandra Metz) adds to her stress. These pressures could lead to a serious error, potentially resulting in her death.

Myrna is the real star of the show
Myrna White (Jeanette O’Connor), an eccentric patient handcuffed to a wheelchair, provides dark comic relief. She is known for her confrontational attitude and claims of violent crimes, such as putting her husband through a meat grinder. Some fans jokingly propose that the entire emergency department might be a simulation with Myrna as the unwitting star of a Truman Show-style reality series, although this is likely a stretch.

Al-Hashimi will get sued
Dr Melissa King (Taylor Dearden) is shown worrying about an upcoming legal deposition, with colleagues noting that being sued is part of medical practice. Dr Baran Al-Hashimi’s claim of never having been sued in her 20-year career raises questions about possible future legal trouble, potentially linked to her reliance on AI, especially after a moment where she froze upon receiving Baby Jane Doe’s test results.
Dr Robby is already dead
Some theorists draw parallels between Robby and Jack from Lost, suggesting that Robby might be dead and the emergency department a purgatory-like setting where some patients pass on and others return to life. Robby himself has said the hospital is the only place where he can truly function and feel alive. His frequent wandering and detached demeanor support this theory. The show’s title could imply a form of hell. This concept has precedent, as seen in the 1980s medical drama St Elsewhere, which revealed its entire run was a dream.
Dr Langdon is a vampire
Senior resident Dr Frank Langdon (Patrick Ball) has returned from rehab but remains relegated to triage. Some fans speculate that Robby’s reluctance to fully reintegrate Langdon might stem from a suspicion that Langdon is a vampire. Supporting this theory are Langdon’s dark attire, limited exposure to daylight, sharp cheekbones, and deadpan responses, such as when confronted about drug theft. While unusual, the show could potentially shift into a horror genre.

Dr Robby will get sectioned (or, sob, die)
Concerns about Dr Robby’s mental health have led to predictions that he may be involuntarily committed to a psychiatric ward, possibly by Dr Al-Hashimi or Dr Langdon, and risk losing his medical license. Others speculate he might suffer a fatal accident, as he was seen riding a motorcycle without a helmet and has lied to patients. The arrival of motorcycle crash victims at the hospital could foreshadow his involvement in an accident. Additionally, hints at suicidal thoughts and preparations for a sabbatical suggest he may be getting his affairs in order. While these theories are distressing, it is uncertain whether the show would remove its lead character.
