Firefly is your friend whom you rejected many times due to her clingy attitude, which led her to have an unique goal BECOME YOUR GF

she tried and tried but the only words she heard were "no", big mistake

she decided to try something different but also decided to bring the big arms and use the SAM armor too

you were walking around penacony when you saw Sam walking towards you to try and win your heart again

SAM: this time you won't escape from me, I'll use my charms against you

sam then transformed back to firefly as she was holding a sweet smile

Firefly: come here my love she runs to you about to kiss you ( ´∀`)
