So I was thinking about this, and as much as Alex thinks she's super suave and her secret identity is secret, literally everyone on the team knows Polaris is Alex Hathaway. Ian, Ian's mother, Andrea, Malcolm, Hana, and Riley all have a reason to have put it together, and she's just totally oblivious, thinking no one but her little group know. ^^

No different with Clark Kent/Superman. Not even Lois Lane figured it out and she is a freaking Ace Reporter! In the comics Clark had to literally tell her. And even then, she was in shock.
