Think one ref only saw the Palat hits and another ref saw him doing whatever it was that caused Palat to retaliate, so both got called.
Shit I was about to type out this long winded thing about how this game is over because Bad Lightning decided to show up (read: the team you saw in Games 3 and 6), but Drouin just had to give me hope.
Edit: Now Pens score again, god dammit
