Lena was surprised that the green haired boy could pick her up so easily, and as he got used to the weight of her weapon form she could feel their souls moving more in tune, almost perfectly matching their wave lengths. She was so excited when he let her rest on his shoulder she almost accidently let off a shot from her barrel, a close save cause the recoil probably would have hit him in the head. 
"Oh your the first Meister who has been able to pick me up! Oh my god this is... I don't know, you need to be my Meister! Please Simon?"
She was almost ready to beg, her excitment barely contained. She was already imagining how powerful of a team they would be under Lord Death's guidence.
