Alex Danvers Seemingly Getting New Supersuit

Chyler Leigh just posted this on Instagram without context. I have a lot of questions.

• Does the costume come with powers?
• What about a secret identity?
• Is that a cape?
• Is it a one time thing?
• Why is her hair different? Is that part of the secret identity?
• What is her superhero name?

UPDATE: It's definitely from whatever episode they were filming Wednesday (probably #16) and that is indeed a cape.
