Tough...sure that's a good enough word. I'd say experienced. Mei's the only one with bond experience and that's with her brother. Lame. Brenda's a complete novice. She's only used her power on Mabel once or twice when they were really young and she got in trouble for that. Lisa used to bond three people a day just to carry her around. It's like putting up a super strong toddler against a trained mma fighter....actually I don't know if that analogy makes sense.......close enough.
