Looks like they're headed to the other legendaries with Suicune. Spike returned all his Pokemon to their respective Pokeballs & followed the others. Weren't the others coming?
"I hope this doesn't go wrong." Said Latias telepathically to Mew as she went with the others.
"So, how good are your Pokemon?" Spike went & asked Valorie a question. If she was new, Spike had to make sure he knew everyone, especially newcomers to the team. If possible, he might challenge her to a battle.
