I haven't played Warhammer since November, so I'm a little rusty. A situation came up in my game last night that I would like clarified. I charged a single rank of Saurus Warriors with my Greatswords to the front and Knights Panther to the flank. My Wizard Lord was on the corner of the Greatswords adjacent to the Knights Panther. I issued a challenge with the Wizard Lord, which was accepted by a Saurus Hero positioned at the end of the rank in contact with both the Wizard Lord and the Knights Panther.
Now that the Saurus and Wizard characters are in a challenge, the Knights Panther are no longer in contact with any other Lizardman figures. May the Knights Panther fight the rank-and-file at all, with or without the challenge? I believe that the Knights Panther couldn't attack, but this seems very unrealistic.
