Pretty amazing to see Hiro actually make a significant change to the past, though he was kinda forced into it. I thought it was well done how Ando thought nothing had changed. To him, the slushie had always fell on that "random guy", who he didn't know was Hiro. Only the time traveler is aware of the previous reality. It's a good sign and I really think time travel can be used well again, and it'll be interesting to explore what small changes can be made without disrupting the key events.
There are some interesting things to wonder about, such as how this affects Ando's views towards Niki in season 1 or his relationship with Kaito, etc. Though, I think generally everything makes sense to have led to the same basic story we are currently at.
It'll be interesting seeing Ando from this new perspective of actually being in a relationship, and with is best friend's sister to boot. I got a sense from the past interactions that there was some chemistry between Ando and Kimiko, and if all that was stopping before was one slushie accident from the past, maybe Hiro changing the timeline was meant to occur to correct and bring the two together. Though, I imagine it must feel weird for Ando to hear from Hiro that he's the reason Kimiko has liked him for 14 years.

I think it's cute that they're together, but I an't be the only person out there whothinks that the reason she couldn't stand him in the earlier seasons was because he tossed a slushie on her.
Well, I wouldn't think it would be the only reason. Events probably compounded from that moment onward to solidify her view of Ando.
