Gabe blinked at Zoe's appearance in surprise and concern, and for a moment her words didn't really mean anything to him. What would he have- but Gabe knew the only thing he'd have anything to say 'I told you so' about. Chance. And with how Zoe looked he could guess what had happened.
At least, he could guess what he hoped had happened. He hoped they had broken up and not that Chance had done something horrible to her. Because the first option was better.
He walked over and wrapped his arms around Zoe, pulling her close and holding her tight. Laying a kiss on the top of her head, Gabe didn't say anything, just let his friend cry.
