Tahm's Knowledge of Lissandra

Spoilers ahead. At least I think they are, for those who are new or haven't kept up with Lissandra's story.

So with all these threads going on about Yordles and Tahm, can we get down to some more speculations? Some involving our favorite Queen of the Freljord perhaps? The story involving Lissandra has come and gone, her bit with Ashe and Sejuani are still there but it no longer plays a prominent role in the lore, since it has taken a break. In other words, it's no longer center stage. (The stuff that happens on the Howling Abyss doesn't count!)

Going back a few champions, if memory serves me right, Gnar was attacked by some entity rumored to be connected to Lissandra's Watchers. He was encased in true ice by Anivia, or so says the Wiki, but he was unfrozen to help fight against Lissandra.

Then there's Kalista, who immediately lists Lissandra as a rival. She says, and I quote from the Wiki: "We see the course of your deception, Ice Witch." "Your duplicity ends here, Lissandra." "We see through you, Ice Witch."

No one, as far as I know, had called her Lissandra up to that point. (Red flags should be going off right about now.) Everyone knew her as the "Ice Witch", never as Lissandra, but Kalista shows up and with the power of a Pink ward calls her out. Kalista knows something about Lissandra, heck maybe EVERYTHING. Kalista, with whatever magic power she has, sees right through her facade and knows who the Ice Witch is, this revelation in and of itself would be enough to destroy Lissandra, given her participation in the League of Legends. But nothing has occurred since then.

Then Tahm shows up and his only responses to Lissandra are as follows (straight from the Wiki): (Enemy) "Good ideas fall from you like pudding from a harpy." (Ally) "Could I offer you a bargain to replace your previous engagement?"

We know what Lissandra wants: to rule over the Freljord and the world in the end. She wants Ashe dead and Sejuani at her feet, or maybe even both dead. That would be her "previous engagement", no questions asked. But what could count as a "bargain"? Her eyesight? Ashe's or Sejuani's death instead so that she has to work for her real goal? Whatever it may be, it would of course come at a price. But what more could she lose at this point? She's just biding her time and waiting for the right time to strike and at this point we have nothing left to do but wait as well.

Tahm, who can ultimately help Ashe build her empire and who can help Gnar find his place and maybe even the killer of his family, has all the answers we need but he's not giving us anything.

How about you guys, does anyone have any thoughts they'd like to add or something I've missed that could shed some more light on these matters?
