The techromancer was teaching Bea to hone her shifting skills.
That was the only way she could escape her fate at the hands of the Scourge Moderators (or the Surge Team as they had been called in other iterations of that reality).

“Focus!” he told her “only a sheet of paper will do for now.”
“And you don’t actually need the cackling for it to work.”
