Blue Boots in Songs of Love and Death, SPOILERS for everything

[Farseer]

As much as I'd LOVE for it to be Burrich's Just (and more than possible, seeing as TM was fifteen years after the Farseer trilogy?), Robin does have a habit of duplicating names over one or two books and this may just be another case? Examples of this would be:

1. Hest was the name of a member of the Six Duchies guard in TM and then the name for Hest, the bad guy, in the RWC

2. Malta was used for Malta the Elderling and also Fool’s horse

3. Chivalry was used for both Burrich’s lord (Prince/King-in-Waiting Chivalry) and also his eldest son

4. The name Bolt was given to Regal’s henchman and also to Bolt, Vivacia’s dragon

Given that Robin has said that "Blue Boots Falls during the Assassin’s Apprentice/ Royal Assassin time" we can lay this question of Lord Just's identity to rest. The Lord Just from Blue Boots cannot possibly be Burrich and Molly's Just, but simply someone who shares his name.
