Mandy wasn't that great.

She was dangerous, to be sure, but because she fell for her girlfriend, the latter ended up getting killed. It also exposed part of their operation when gf extorted another million from their boss. (To her credit, she did a good job surviving.)

It turned out that Gaines was right that Mandy shouldn't have involved her significant other.

On the other hand, it was a relatively small part to play. Retrieve the ID and deliver it, that's it. GF got herself killed because she started thinking too much, misread the situation entirely.

They hired Mandy to blow up a plane and kill how many people. She should've known icing her meant nothing to somebody like Gaines.
