Please don't forget us

I've had a special affection towards these two ever since I saw scenes of the Pokémon Heroes movie. The fact that these two went through excruciating challenges to reunite with one another, only for Latios to sacrifice himself at the end was heartbreaking. I know a fair number of people and Pokémon alike gave up their lives to prevent disasters in the Pokémon anime, but I find it more depressing considering they're siblings that were split apart. 

I won't ever forget these two and even then, I can't since I just got the Toy Pokémon version of Latios on Pokémon Rumble World today even though it took every Poké Diamond I had to get him... Does it make me a little sadistic that I used Latias to catch Latios?
