I could only see SH betraying or acting against you out of desperation or self interest, not ideology, despite the god worship I'd say she's CN from her behaviour maybe, I could even see her as CG but hiding it if it wasnt for clerics needing to be in neighbouring or same alignment with diety, but that rules out CN too, so I'd guess shes NE, Evil in that she's selfish but not enough to wish harm to others or enjoy seeing it? It's awkard to place her given the little information so far. But she's definitely not evil laugh evil or anything. While she worships Shar, that doesn't equal wants the whole world and everyone in it to die, she's not a frothing doomsday fanatic and seems way too selfish/proud to be cool with the world ending in her lifetime.
With Lae'z I'd only see her betraying us if a superior rank Gith told her too as she's loyal to that cause above everything. I can see that by the time we get rid of baby frogs (if ever) she might be as loyal to the party as the war as I'm guessing that's her arc, either that or getting burned by the gith so going vengence but she seems L to me, but LE, LN or LG idk. I know her approval probably rules out LG, but given Gith have alien morals that could be LG for her, we've seen LG humans who are pro- killing innocent goblins/drow/etc in the past, Lae'z could be LG as a send up to Keldorn and the bigoted paladins of BGpast.
