Disney Infinity Fans

So I was recently playing DI 1.0 on the wii with my 8 year old brother. I was playing as Ralph and he was playing as Elsa. We were trying to recreate the ice castle from frozen, and I walked over to where Elsa was and when my avatar got close to Elsa he said something like "gosh! you sure are pretty" in an embarrassed voice like how figures from the same franchise talk to each other except Ralph and Elsa are NOT from the same franchise! So what's up with this? Has anybody else had this happen? Does Ralph have a secret crush on Elsa? Please tell me, I'm so confused! (BTW he did it a seconed time yesterday, to Elsa again, and he has never said that to any other character)

Ralph has a lot of reactions to other characters. Whether they are from his movie or not!

All the characters interact with each other in the toy box, its the little touches that make the game great

This is one thing I love about DI, and it's been confirmed some 1.0 characters will interact with 2.0 ones, also 2.0 with 2.0!
