I don't know if it's the same line, but the last bubble sounds similar to Sousei no Aquarion's opening theme.
With that kind of line, it's the same as saying "Please suspect me."Mikuru will never get close to deceiving anyone either.Thanks to you two I've figured it out. This is a good moment.That was a slip just now, Koizumi-kun.Well, there was something off from the start.Trying to put one over on me!You're ten thousand years and twenty million lightyears too early for that!!
一万年と二千年 ("ten thousand years and two thousand years") is a famous line from the OP theme of Sousei no Aquarion, unique in how it separates the normal counting. Haruhi, of course, appropriates it and mangles it.
