Teren thought for a while on how he would answer. For Iesa, everything is shrouded in mystery like a thick fog covering a whole island.
However, unknowingly, she arrived at that island. Even though there are thick fogs wherever she looked, she began walking and was eventually discovering, no, rediscovering what that island is.
Teren has yet to tell her anything and he doesn't intend to or the worst-case scenario might spark, leaving him dead or her with no other options. That's what he fears the most.
'The Great Spirit of Mind-Altering is weakening. She should be the most affected of all. She dispelled my second, though weaker, alteration. It's only a matter of time before she learned about her past...'
While thinking so, Teren found a problem. He didn't notice is earlier maybe because he was flustered or because it felt natural. But it shouldn't.
