It doesn't make sense. Much less why she would even consider it worth keeping (besides the fact Chibi!Lulu is uberly adorable).

Unless of course she met Lulu when he was younger, like when she first got the device or something to that effect. Cause it looked like she went through afew clicks before she got to that one.

And she does look alittle like Marianne o_o I'm not putting anything past nobility. I don't doubt they're all related in some way, so its quite possible.
