A Blanketed Forest is in play in the current battle. My opponent takes an action to destroy one of personalities and I react with a Shattered Ranks. The Samurai can't move home due to the Blanketed Forest effect but does he bow?
Shattered Ranks While focused in a duel, this card’s Focus value has a bonus equal to the number of Followers attached to the Personality who focused it. Reaction: Before a Samurai you control at a battlefield is destroyed by an action, target and destroy a card attached to him: Negate the destruction. Move the Samurai home, bowed. Blanketed Forest Forest Winter Terrain Battle: The snow blocks travel, negating units' movement to or from this battlefield.

No, due to the way effects worked in Lotus when Shattered Ranks was written.
