[Keeping Mikami's personality and occupation in mind, it seems fairly obvious that he isn't here for recreation, but that's a thought Light keeps to himself.]

Ah, so they caught your attention as well. That's even stranger, then, that people representing at least two independent organizations wanting a closer look at InGen's activities were randomly selected to attend. [Technically speaking it's at least three organizations if he's counting Interpol, but it's not an affiliation Light chooses to advertise.]

If we assume that InGen ran background checks on all of the chosen guests, then the message they want to project is that they've done nothing worthy of suspicion. [In other words, they've issued a challenge. Light pauses.] Perhaps that's true, perhaps it isn't - either way, I intend on keeping a close eye on their activities while I'm here. I'm glad to hear another person will be doing the same.
