Malazan Empire: Trake/Treach & Rallick Nom - Malazan Empire

I was wondering if there is any significance to Kruppe having given Rallick a Tiger mask to wear to the ball? The Tiger of Summer has vacancies to fill?
Rallick and Vorcan now being ensconced in the Azath House as was Kellanved and Dancer too... closely followed by Korlats explanation of what happened to the latter seemed very pointed.
No doubt it is all a product of an over-active imagination (mine).
