If everyone comes out to watch it defeats the purpose of doing it out where it won't damage anybody or anything. That said, as long as you understand that things could go wrong and you might, but probably won't get blown up, you can come. Wouldn't be right to say yes to Stark and no to everybody else. Putting your name on a settlement shouldn't give you special privileges after all.
I'll do my best not to blow myself up, though I don't know what I'll do once I'm not new here. I'll have to think of another reason not to do it.
