However, Aeryn's prowler is caught up in the stream of Moya's starburst and is towed along with the escaping Leviathan. Aeryn is brought on board Moya as a prisoner, but when she and Crichton encounter her commanding officer Captain Crais, she defends John from Crais' allegation that John deliberately attacked and killed Crais' brother, saying he is not brave enough or smart enough to have done so. In return, Crais declares her to be "irreversibly contaminated" from spending too much time with an unknown life form, which means a death sentence. John Crichton and D'Argo soon escape the Peacekeepers again and, having nowhere else to go, Aeryn reluctantly becomes a fugitive alongside them.
