Slap him, and , what, get her friend Aaron more upset with her as he's obviously confused as to why she's protecting this Ted guy? Smart.
Elincia, if you can, talk to Ted, do what everyone else here is saying. Talk to him, ask him what's up, heck, tell him you like him if you feel like it. If he still acts like a complete douche, then Aaron's gonna kick his ass. Not much you can do to stop that :E
If he does acknowledge that he was being a dick hole, and apologizes, tell Aaron, have Ted apologize to everyone else, problem solved.
This is only gonna go one of two ways :U
