Act 3: Why does Antonio say he folllowed Sebastian despite the danger?

Antonio is slow to leave Sebastian's side, as he fears some accident may happen to Sebastian since he is completely ignorant of the country. Sebastian wants to go about and see the sights, but Antonio tells him that he cannot; Antonio confesses that he was involved with some piracy against Illyria, and that he is wanted by the Count because of it. Antonio proposes that they meet up at an inn in one hour, and that Sebastian can wander about until then; they part, hopeful of meeting up again without accident. (sc 3)
