Love Island contestant Greg O'Shea left the villa and returned home to Ireland to attend his grandmother's funeral.
The rugby player from Limerick, who is coupled up with Amber Gill, flew from Majorca to Dublin on Monday following news of the death.
Some 24 hours later Greg was back in the villa but it was not clear whether he would appear in Tuesday night's episode.
Speaking to Limerick radio station Live 95, his father, Niall O'Shea, said his son had asked to fly home because he is a "very good family man".
The station said Monica Ho died at Talbot Lodge Nursing Home in the Irish capital on Friday, the Liverpool Echo reports.
Mr O'Shea also praised ITV2's production team for its handling of the situation, describing them as "very helpful".
He said: "Greg is a very good family man and his mother wanted to make sure he was there because himself and his nan got on well.
"So, in fairness to ITV, they were very helpful. They were very helpful... They organised to fly Greg out yesterday."
A statement from ITV said: "Owing to a bereavement, at the wishes of his family, Greg was away from the villa for a day to attend a funeral.
"Everyone at Love Island extends their sympathies to Greg and his family and we have since welcomed him back to the villa."
* Love Island, hosted by Caroline Flack, continues on ITV2.
