Surely you mean the class of 2017? LOL
In Laura's defence, her dealings were a little more direct. They iced her boyfriend and gaslighted her. Sure, Chad didn't do it, but he proudly boasts the name. If I were Laura, I'd be leery of Chad, too. (And for all we know, the last info she got on Chad's doings might have been when he faked his brain tumour.)
This is true, too, though I still say I'm team Laura on this one. Mainly because her experience was so close, and there has been a litany of "non-evil" DiMeras through Salem...almost all of whom turned evil when it suited DA PLOT. LOL
