Figures. Runaway, rocky relation with parents etc. What would be interesting to observe is when she is sent back in time to fix regrets how will this effect (future) Dr. Tom. If changes are radical enough Tom's life would be different and he may not even be in place to become a doctor, thus changing Erica's life as well.
Though I doubt show will touch on this.
EDIT: This also explains why Dr. Nadia was so determined to see Dr. Tom retire. She didn't want him around when her daughter was being treated as he wouldn't be able to stay away and would keep butting in on Erica.
