Effervescent

Effervescent is a hero working for Foresight in the City.

Personality
Effervescent comes off as pretty stand-offish to Victoria, on one occasion refusing to shake her hand. Further she keeps a cool head in situations where other people start sreaming their head off.

She has a substance abuse issue and took steps to make sure she wasn't in a situation it could flare up.

Abilities and Powers
Effervescent could manipulate emotions, specializing in incapacitating people. Like Gallant and The Heartbroken she could read emotions, able to do crowds of people and very far away.

She can read people's emotions en masse and at significant range being trusted with patrolling at the Portals. she was refined to the point she could also act as lie detector.

Effervescent was unable to get a consistent read on Victoria or Mr. Drowsing, likely due to their own master powers. This likely means she would have issues with other Emotional manipulators as well.

Early-Ward
Effervescent is first introduced during Victoria Dallon's interview with Foresight. There, Effervescent comments how, while better than most when it comes to getting a read on people, they are unable to get a consistent read on Victoria. She surmises it might be due to her emotion manipulating powers. This uncertainty is a contributing factor to them voting 'no' to offer her a space on their team.

Post-Time Bubble Pop
Met with Victoria and Tattletale, and discussed possible recruitment interference in regards to Ratcatcher and Big Picture.

Effervescent moved into The Wardens Bunker on semi-permanent basis, since she was not able to maintain conspiracy due to personal reasons. She assisted in arresting Orchard and Victoria's later dealings with Mr. Bough.

She was present during the assembly of the second team aiming for Teacher's stronghold, confirming the monumental task of countering him.

Trivia

 * Effervescent derives from a latin root that means boiling up, this is why it evolved as a description for carbonated water and various sodas.
 * Incongruously, given the her personality it is also used to describe someone who is vivacious and enthusiastic.
 * It works perfectly as a description of emotions bubbling up however.
