However, a scene DOES occur for an agent that's pursuing them called Agent Zero. She is played by the same actress who was the blonde speedster from Heroes; and at some point she sympathizes with the princess' plight and decides to let her and her group free from interrogation (or something like that). To cover up there escape, she asks them to tie her up and later her two agent friends walk in on her where she asks them to untie her.
Bad news is that I've done a bit of searching and found episodes from various parts of the series EXCEPT for this one. Funnily enough, the whole second half of the show is available on TheEscapist page of metacafe's website, starting from ep 13; which alludes to her capture via the agent's dialogue, which is what clued me in to when the scene very likely occurred. I found a website called FantasyWebSeries that purportedly had the show but it's videos never loaded up for me; if anyone else can conjure up a way to find it then great but otherwise I'm out of tricks.
