Production ordered each housemate to nominate three peers with 3, 2 and 1 points, replacing the prior format and disrupting Cuarto Día’s planned block vote. Guana won the leader challenge and holds immunity this week with the option to save someone from the block later in the cycle. Viewers can vote to save nominees on ViX and broadcast channels, with ViX Premium offering multiple daily votes during designated windows. Tensions inside the house intensified as Elaine Haro aligned publicly with Cuarto Noche and traded barbs with Facundo in a kitchen exchange. Facundo traded a MXN 30,000 prize for a two‑minute call with his fiancée after an initial misdial reached a man, a moment that drew heavy online reaction and a show announcement that the cash would be donated to an orphanage, while separate social backlash targeted Cuarto Noche over a cinema-session clip and journalist Joanna Vega Biestro reported receiving death threats from an account she linked to Aldo De Nigris supporters.
