Forum:Possible new "younger brother"

In Manga episode 614, whats done is done, In the opening title we see makino with a baby in her hands.

If it is her baby and since Luffy might have seen Makino as a sort of mother figure as well as dadan this could mean that him and luffy will meet up and luffy will act like an older brother to him

What do other people think, this is just a guess. J>B.
