This may take a bit of explaining, but stick with us, it is the best. The blonde to the right there is Hockey Queen Elisha Cuthbert. She is currently engaged to Maple Leafs captain Dion Phaneuf. The brunette sitting one row below is married to Maple Leafs goaltender James Reimer. Both men were involved in the final play of tonight's overtime loss to the Bruins.
The game ended at 13:06 of overtime when David Krejci scored against Reimer. But it was Dion Phaneuf's overly aggresive and self-decribed "bad mistake" that lead to the goal and this icy exchange of death eyes between the two women. Reimer's wife looks back almost instantaneously and catches the eyes of Cuthbert. It is a mess.
Here's another angle that really captures the what the fuck was that?-ness.
Update: Reimer is saying both she and Elisha were reacting to some rude comments from another person. So, maybe they don't hate each other?
