Squalo wouldn't say that he missed Alo, he didn't treat his box animal like a pet, but Alo was part of him that had been missing and having her back felt like being whole again. The Great White soared through the battlefield on Rain Flames with Squalo on her back. It was the fastest way for him to travel, and his cell had been ringing enough for him to be annoyed.
He didn't have to show up, if the storm guardian was at all competent he shouldn't have to call. Squalo could have easily ignored the call (Which it must have seemed like he did because he pointedly hadn't answered.) and let the Neo Vongola's right-hand fend for himself. Like he should. But Hayato Gokudera was Vongola and he was a fighter, albeit annoying, and with the absence of the Varia those in the Vongola was all Squalo had. It was gross to think about it like that.
It hadn't been hard to find him when Alo knew who she was tracking, and once the boy was in sight Squalo jumped from the sharks back while she rushed into some incoming enemies with open jaws. Standing, Squalo flexed his prosthetic hand as he approached Gokudera with a sneer.
"VOOIII!! You better be dying brat!"
