Hamish is only competitive on the pitch (and with Cass outside of it, but that's sibling rivalry more than anything else), so he's all for chilling with Henry.
Sounds good with Samir! Oh, and by the way, he's always getting into the kitchens and asking for food (to the point that he's given them some recipes of Egyptian desserts) so that's something else he and Henry can bond over.
Zoe has no problem with playful people, so I can see them getting along just fine.
