He (quite reasonably) assumes that the rescue site too seems to be required to be "off to the side" with the hazard host. A look at the DM rules on Prisoners does not bear this out, however:How can an agent return to that site , when the site is put off to the site with the hazard host?TO GET YOU AWAY -Permanent-event (R)
Tap an agent at target company's new site. Agent may attack (not counting against hazard limit) during the movement/hazard phase. Attacker chooses defending characters. A successful strike doesn't wound the defending character,instead the character is taken prisoner at one of the agent's home sites of the attacker's choice (regardless of site's location) and the agent returns to the same site. Rescue-attack: Same race as agent - 3 strikes with 8 prowess.
The DM rules specify that the prisoner is set "off to the side", but not that the rescue site is. However, it is unclear where else the side would be in this case. Is it still considered to be in the location deck for other purposes? I can't imagine this is right. You shouldn't be able to visit a site you've designated as a rescue site. But then, by the same token, you shouldn't be able to send the agent back to that site either. After all, you couldn't move the agent there!Certain hazard permanent-events cause a character to be taken prisoner – these are called ‘hazard hosts’. A character taken prisoner immediately leaves his original company and is placed under its hazard
host “off to the side.” Additionally, the player playing the hazard host must take a site card from his location deck and place it with the hazard host – this is called the ‘rescue site’.
Perhaps this will work: the agent is now considered to be at that site, as if you had revealed him/her at the site without the site card. But how far should this analogy go? Must the agent be discarded at the end of the turn? Here's the relevant DM rule:
Once again, I'm baffled.If one of your agents is revealed before it has moved, you must immediately choose which home site it is at – place the appropriate site card with the agent. If you do not have such a site card in your location
deck, discard the agent at the end of the current turn.
