Wow, going to talk to everyone one way or another, Senku, is that a threat...

Thankfully Inigo sure doesn't have to be threatened into social interactions. Or even pushed into them, really, because the main reason he's here is to talk to Senku, of course! He's not too sure how he would have felt about a party right now otherwise, but it'd suck to just ignore the birthday of one of his friends, right?

So rather than having to come up to him, it's Inigo who seeks out Senku, a smile on his face.

"Senku, happy birthday!" He motions with his hands a little, to show they're empty, before continuing with a slightly awkward smile-- "Forgive me that I didn't get you a present." It's kind of hard on this train, after all.. "Let's call all the stuff I gathered for you before a.. very early birthday present!"
