They should probably practice together. Rachel isn't any better than him, really. Despite having training opportunities with a number of different fighters for over a year, she always quickly forgot any techniques that got in the way of morphing. Between her human body and the arsenal of morphs in her DNA, it was no contest, which one to choose. Be a skinny teenage girl or a massive fullgrown grizzly bear?

Yeah. No contest.

Still. She has a collection of knives that Dean showed her how to clean and sharpen, and the gun Jo showed her how to take care of, and a little bit of technique from Dick that combines her gymnast's knowledge with actual fighting.

And it's still lame in comparison to the bear.

Which is why Tobias is working out and Rachel is cleaning the weapons. Because 'sparring' with her housemate/boyfriend hasn't yet occurred to her, but she likes being outside when he is and watching him work.
