I'm probably the only one who doesn't have much complaints so far.
Maybe bc like Thisa's, I'm always questioning and cautious of certain things depending on the situation. If I was in her shoes, I'd always have my guard up too, considering how my kidnappers in my mind may have killed my sister then took me to the island they're from and grabbed my son too.
No matter how hot Weir is, I'd be thankful for his protection but be cautious and suspecting of him too bc he's still letting the two guys who kidnapped me roam freely in my eyes (even tho we know it's his way of keeping them to see if they slip up or not but Thisa's character don't know that)
So, personally, she's acting reasonably.
But like everyone, i'm glad she finally told him her identity.
