Dean couldn't help but smile when Sinistra seemed to give in and use what he thought must be her natural accent. He'd stirred in his own sugar and was just holding his cup between his hands for a few moments. "I'm saying nothing. I coul' return wit' a nice Caribbean leelt," he replied, letting his parents' predominant accent drop in. His voice returned to normal as he continued. "It's not really mine though, I lost it soon after I started nursery school, according to Mum." He shrugged. There were odd words where he couldn't help but use the accent, but it was almost entirely eradicated and replaced by the not-so-posh end of London.
He sipped his tea and was pleased to find it was strong enough for him. Reaching for a biscuit for himself he was undecided for a second, before giving in to the pull of the chocolate ones.
