Maya knew that she was pregnant with their daughter at about seven months. But she also knew that she had a choice to make. Either give the baby a chance to live or die.
That night, they had a talk. She told him the two choices that they had been given. " Tai, it's either going to be me or the baby who will survive the birth. And frankly, Tai, I'd rather have the baby survive the birth this coming December. And I've told the doctor the same thing."
He nodded in agreement when he got the call over his Tac/Com to get his ass moving. And of course, Angel Rose Kaliso was born on the same day that E-day started. Maya died from bleeding after their daughter was born. Matthais was told to raise his half sister at the dojo where he was being left at the time. And he did.
The dojo was of course, a ninja dojo and she was to be trained as a modern day ninja, as she gets older and wiser too.
