Shocked, Gavin darted his gaze between Gabriel and Tristan simultaneously. His lips parted in disbelief, but soon he pursed them close when suddenly Tristan spoke.
"Would you mind explaining, little brother?" he asked seizing Gavin's attention.
When Gabriel found Bianca, he ran a thorough investigation, gathering as much information about her, and in that piece of detail, he learned about Jenny Han, a fellow doctor and also Bianca's only friend.
Gabriel didn't want to his guard down, so he asked his men to monitor everyone, especially Doctor Martin and Doctor Jenny. During that investigation, Gabriel learned about Gavin's involvement with Jenny, and a few days later, he learned they going on a blind date.
With Tristan's eyes scrutinizing him dangerously, Gavin gulped. By the looks he could tell his brother knew everything and there was no reason for him to keep hiding the truth. One way or another Tristan would come to learn everything.
