Is it possible that Mab is Lara's mother? I don't believe Lara's mother has ever been mentioned. As noted elsewhere in this topic thread, there are times where wintry words and phrases are used to describe Lara, including by at least one of the Fae (Toot-Toot).
Being Lara's mother would also explain why Mab couldn't marry Lara. You know there was a reason for Butcher to insert that curious and awkward exchange into Battle Ground; wholly unnecessary other than to provide some clue or foreshadowing to the readers. What other reason could be something that would be fair to readers? Later explaining with saying *because magic* or *because an offspring is needed* wouldn't be a payoff for the wording of that exchange.
And it seems clear that Mab as the Winter Queen can get pregnant since she gave birth to changeling near-twins Maeve and Sarissa - unless their father was Fae and they were conceived when Mab was human and before she assumed a mantle, which was no earlier than the Battle of Hastings in 1066. But that would mean that Sarissa was a changeling for more than 1,000 years. Maeve's recitation of Sarissa's pursuits suggests many decades, maybe a few centuries, but I don't think 1,000+ years.
