Throughout the series, Bonar kept her daughter's bedroom as a shrine and pretended to receive emails and packages from her, when in reality Tamara was long dead. A flashback sequence in the finale revealed that Bonar's daughter, Tamara, came out as transgender and even went through a gender transition into Timo, which was unacceptable to Bonar. As she longed to get her daughter back, Timo found acceptance in his friends and the school counselor, Lali.While Bonar continued to force feminine things on Timo in Time Flies, in hopes of reversing his transition, he found acceptance in the outside world, until a tragedy struck him. At a fateful house party, Timo confronted an older man harassing one of his female friends, which led to his death.However, Bonar refused to identify Timo's body in the mortuary when Lali urged her to let her 'son' go. As the grieving mother went into complete denial mode over her 'daughter's' death, she blamed Lali for accepting and encouraging Tamara's gender transition. The Time Flies finale suggested Bonar was more distraught about Timo's transition than his death, which is why she hatched a revenge plan on Lali by poisoning her daughter, Guille.Time Flies ending explained: Ines manages to save her granddaughter View this post on Instagram Instagram PostThe Time Flies finale saw Ines and Manca gearing up for the latter's cancer operation and Bonar welcoming Lali and Guille for her party, which was a ruse to poison Ines' granddaughter.
