Kara replies to Nick's sarcasm about the lingo, "Ha ha, very funny. We are going to follow them in, hopefully orcs go squish when you hit them with a truck."
OOC: I would say it takes place just before the Surprise Round, before the orcs are really even aware of combat. Then we all should get Surprise Round actions in our Initiative order and then Round 1 starts. At least that's my take on it.
