In Rukia's younger years. Renamon takes the young kid and teddy to the young Rukia's bed.

Renamon:
-"Remember, Rukia
That life goes by in a heartbeat.
Remember your young years,
Remember the naivite'
Remember that the smartest people are those that keep the curiousity.
Remember the tenderhearted days, life will try its' worste to make you uncaring.
Remember, Rukia
To make the most of one heartbeat."

T.T My gosh, I love Digimon way too much!
