Wow. A maxed-affection Pokemon can lose its paralysis or burns along with increased chances of critical hit and avoiding attacks, and gaining boosted exp during battle.
When avoiding attacks:
<name> read your mind and avoided the attack!
When landing critical hits:
<name> is so in sync with you that it landed a critical hit!
When losing its paralysis:
<name> gathered all its strength and broke free from its paralysis so <trainer> wouldn't worry!
When losing a burn:
<name> blew on its burn and cooled it so <trainer> wouldn't worry!
I'm sure there's one for poison and maybe sleep, but I haven't seen it happen yet. Might also make confused pokemon snap out of confusion earlier.
Also some amusing lines at full hearts when the pokemon is awaiting command in battle:
<name> is interested in the contents of <trainer>'s bag...
<name> looked back at <trainer> and nodded in understanding
<name> is bursting with excitement for the battle!
<name> and <trainer> are in perfect sync with one another!
Between 2-4 hearts:
<name> seems a bit out of it...
<name> seems a little uneasy...
