People propose at fan conventions like PAX, Comic-Con or GenCon all the time. And, yes, many of these declarations of love involve costumes. But a very select few—maybe only one?— have the fan-favorite actress who gives voice to Portal series antagonist GLaDOS singing “Still Alive” along with a banjo. The cuteness here is off the charts, everybody.

After a panel on voice acting at this past weekend’s GaymerX convention, Ellen McLain helped one attendee propose to his boyfriend. It may not be the fanciest, most elaborate Portal-themed marriage proposal ever but folks who were there say that there wasn’t a dry eye in the house.
