Whisper is the best, ya? By far the most the traditionally loveable character in the comic so far, Whisper like all the Custodians is incredibly dangerous. She's an outright terror as a counter-scout, who uses her keen need for company to fuel her ability to find them. Learning about people and how to categorize them is fun for her. She'd make an excellent detective.
Living as a milk hound - her abilities have gotten worse. Milk hounds are not supposed to be fighters. Their newfound ahem attributes makes it difficult for her to adjust her draw in consideration for her new size.
As a side note, part of what makes a Custodian elite is their superior and numerous gear. The gloves, white clothing, mantle of invisibility, and the energy bow were all made specifically for and attuned to her. Sneaking, invisibility, pass without trace, rapid-fire, quick draw, and energy based ammunition. The Prisoner threw them away because they can be tracked.
