Diego came down from the taxi, that he boarded which stopped him in front of Tervin's house, there wasn't much security that was needed for him because he's friend's with Tervin. So, when he entered the estate he didn't find anything unusual or out of place.
Why?
That was because he was too busy calling Tara, but she wasn't picking up his calls, neither was she scared of what he will do for shutting him out. Clearly, this was why he's here to set things straight with her.
When he approached the front door, it was open and he didn't think twice before he entered the empty sitting room.
Nobody was at home?
He thought, but then if there wasn't anyone here the guards at the gate wouldn't have simply let him in, without telling him that nobody was at home.
