Hahaha, exactly! They're similar enough to worry about the other and yet be annoyed that they both kept certain details from each other. (Though I'm pretty sure Tenten isn't as 'relaxed' sleeping, not-lazy as Dash is on most days.) Dash totally admires Tenten's trust and loyalty to her friends too, especially since she's talked with Naruto and a few other ninja. And likewise on Tenten's part; if she ever called for help Dash would be there asap!
