Thank you!

John reminds me of a feral cat, wanting to come in to the warmth but not sure of his welcome.

Mm, definitely. Because he had Atlantis, where he finally felt like he fitted, and then had it taken away - it's a big, big risk to try again with these people. But Cam will win him round :)

Love Cadman, and the camaraderie she has w/ Evan

Thank you! I think they're my favourite not-supported-by-canon-really-at-all friendship :)
