Okay, so...
Because of boredom/boredom/boredom (choose one), I made a list of presents Allen will be giving to people. ... Like, a list with really epic lengthiness thanks to the picture's sizes. Each gift is at least slightly meaningful, so... Let's take Krory's sparkly glittery kira-kira magical flower - Allen knows he had flowers at home and has gardening skills, so even though Krory hated those flowers he had at home, he might still feel a connection to home by tending to a special flower. Miranda's is a pendant - without the chain - because she loved her clock and the design of the pendant is a key. So.
*flails* I hope that explained most of it. .....
.... Oh, but of course, some gifts, like Yachiru's, are Just Because gifts. And some are just for lulz.
AND IF I MISSED YOUR CHARACTER OUT FEEL FREE TO POKE ME. I HAVE SHORT-TERMED MEMORY.
