[Oww...he's not sure if that's a better or worse possibility, to be honest. Then again nothing about this place makes as much sense as it should, so...he frowns now, taking a moment to think before he replies.]

...Mm. Or it just hasn't happened yet--my station is further down the line from Ingo's, so he hasn't arrived at the same destination as mine yet. [Yes, he is capable of making train analogies too. But he's back to smiling again.] But it's fine--even if it's farther down the line...or on a different line altogether, I suppose, it's still the same train made from the same components used to get there. That's how I know he's quite capable of smiling if he allows himself to do so a little more often, because he's obviously still "Ingo"...

[There's a slight pause as he thinks to add, before Ingo could possibly accuse him of this.] And no, I'm not mistaking you for Emmet either, before you ask. You may be twins, but you do have your own individual tastes that separate you from one other, so I'm quite capable of being able to tell the two of you apart. [Not to mention that you both wear different colored jackets anyway, we'd have to be blind to not be able to tell you two apart...]
