[G'raha is, indeed, reassessing his theories as soon as he sees the woman - not biological, but perhaps a family she settled with when she was a little older than the last time he saw her when they were children.

He can see that she's uncomfortable with the affection and wishes there was something he could do about it, he does rearrange the things in his arms so he can offer her a hand, hoping it might draw her away from Val just a little and give her some space]

A pleasure to meet you, Maeve. You must be very happy to see Val again after all this time, however did you manage to find her?
