I have Erik and Landon here! I can also volunteer Stefan for this battle?!
SO. Erik will straight up be using all the power of his abilities against the COS agents. You got bullets? They're coming back at you. There are wires in the building? Now they're strangling you. He's mad. These are his people and he's feeling pretty ruthless.
Landon isn't good at fighting. He gets a 10. I imagine it's fairly early. I'm actually cool with him "not making it" because he will straight up be reborn from the ashes since he's got that ~Phoenix magic stuff.
