Brother or sister??

After spending a wonderful time in Summers mansion, Jean and Scott went to Grey mansion. 

Though Jean is not a Grey anymore and she has passed all her shares and responsibilities to Cassandra, she is still a family member. 

Everything has been pretty well in Grey's side too. After Vanessa is taken away and Cassandra started to work hard to achieve her goals, company started to grow up to its pinnacles again with help of Jean. 

Now, Cassandra is the CEO of Grey corporations and she is married. The occasion for the visit is that they just found out that she is pregnant. 

"Mom, am I going to get a cousin sister?" a five years old Jason asked Jean excitedly. 

"Might be. But, baby....we cant tell now itself. It can be either cousin sister or cousin brother" Jean pinched his cheek and lovingly said.  

"But, I want cousin sister" he pouted.
