Haruki laughed as she answered his comment about the name, "It's not just you. I think the name Tiny would best fit a Snorlax in this case," She sighed after calming down a bit, and she muttered "Hopefully, Spitfire won't be too angry with us though..." 

When he started walking towards the portal (now seeing the black lines around the rift and that it was hovering in mid air by a few inches), she rushed over to him, and she placed a hand on his shoulder, gently getting him to stop. She answered him, "Woah! Wait a minute, Almond!" She explained her reasoning once he stopped, "Firstly, we don't know for sure where that leads exactly. For all we know, it could lead to another world completely, and the portal could close behind us after we go through, considering the last portal. Secondly, Pewter City is very close to Pallet Town, according to the map, so this portal is much more likely to be the exact opposite of a shortcut. Thirdly, if that does lead to another world, then what will happen to Tsunami, Walnut, and Spitfire?"

She then got to her point, "I think we should continue down the path to Pewter City. I'll mark this place on the Pokegear, so we can come back to the portal, when we're done with those shadows here,"
