I think it would be funny if the whole Courtland-Gentry family has the opportunity to reunied with Grace in the ship, and that they get to meet the people of the Project Hail Mary taks force.
Maybe the families and loved ones of the people working there were threatened and they needed to live in the ship until Stratt could recolated them safely.
And everyone was suprise to see all the family that Grace has: Two older brothers, Court and Lars, a twin, Colt, a little brother, D ( Driver who i believe was named by their abusive father and since he doesn't like to be call junior goes by D or Driver), an weird cultish and kind of depressive uncle, Ken, another weird but different weird uncle, Holland, and cousins; Holly, Jacob, Sebastian.
The Project Hail Mary's taks force is very curious and confuse, it seems that Grace family has a facility for been action men who can use guns, or do crime or be very good singers, or sweethearts, and the awkwardness may by heritage by this point.
And then Grace shows them a photo of his granfather Noah, and the Task Force is sure that that man has the strongest DNA registered.
