Yup- that worked! I ended up just copying all the style from Genericons.css to get it to look exactly the same as the others.

.pis-comments:before {
	display: inline-block;
	width: 16px;
	height: 16px;
	-webkit-font-smoothing: antialiased;
	font-size: 16px;
	line-height: 1;
	font-family: 'Genericons';
	text-decoration: inherit;
	font-weight: normal;
	font-style: normal;
	vertical-align: top;
content: "\f300";
}

Thanks so much!
