The Surprising Causes Behind Liam’s Vomiting


Liam’s medical situation escalates drastically, as his parents report that his vomiting has progressed to episodes of throwing up blood. Upon conducting toxicology screenings, the medical team discovers traces of ipecac, indicating that Liam’s condition is self-induced. While he initially appears to corroborate a bulimia diagnosis, it soon becomes evident that there is a more complex issue at hand.
Dr. Charles ultimately deduces that Liam is engaging in a form of self-administered conversion therapy. He explains to Frost that this cruel practice mimics Pavlovian aversion therapy, whereby individuals are conditioned to associate same-sex attraction with feelings of nausea. Liam’s actions stem from a desperate attempt to fit into his parents’ expectations, seeking to suppress his sexual orientation due to their lack of support.

Upon discovering the emotional turmoil influencing Liam’s self-harm, Frost questions whether Liam should be placed under a psychiatric hold. While Liam’s mother shares this concern, Dr. Charles opts against such a measure, believing that enforced confinement could reinforce Liam’s harmful perception of his sexuality. Instead of offering protective intervention, Charles misjudges the situation, risking detrimental consequences for Liam’s mental health.
The fallout is immediate and troubling. Although Liam’s father eventually embraces his son’s identity, his mother’s reaction is less supportive, framing Liam’s sexual orientation as a problem he must “fix.”This public confrontation could leave lasting scars on Liam’s psyche, and the tension escalates into a heated custody dispute right in the hospital hallway.

Dr. Charles’s actions throughout the episode warrant scrutiny, particularly his failure to place Liam under psychiatric observation. This moment reflects not just a lapse in judgment but poses broader implications for his role as a physician. Although the episode concludes with Liam still at Gaffney, suggesting potential future appearances, his apology for not being able to “fix”himself highlights that his journey toward self-acceptance is just beginning.
