If an attacker stealths passed Walder Frey, and the defender defends with enough that they will be winning the challenge, does Walder Frey do nothing?
Stealth keeps a character from defending the challenge.
Walder Frey's text:
After at least 1 defender is declared during a challenge, kneel Walder Frey to have him participate on the side that is currently winning the challenge.
I say he does nothing because he cannot defend, but I am curious what others think because the effect is passive.
Also, a fun note - Declare a Naval defender and he joins the winning side immediately. :-)
