Hi. I have just finished the Latios/Latias quest at Alto Mare but I haven't caught those two yet. So is it possible for me to change Latios and Latias's forms when the event is over? Thank you so much for helping me!

Thank you @Norex @Midsommar it worked. Thank you so much for helping me ^^

Here is my Swadloon. As I searched on Wiki, it can evolve by maximize its happiness. It is obvious that its happiness has already reached the max point. But when I use Rare Candy on it, it can't evolve. Anyone help?
