Samchelpez as in a love triangle with Rachel in the middle or as in romance between all three of them?
Samchelpez as romantic between Rachel and Sam and Rachel and Santana, with Santana and Sam being close and affectionate. Or at least that's the ideal, as you know the shifting and moving around to make the relationship work could have some trials and tribulations to get there!
But yes. A romance with all three.
If you're asking about the bedroom, sometimes it's just Rachel and Sam, or just Rachel and Santana, but if both Santana and Sam are with Rachel at the same time, I see them as working together but not touching each other.
...Like my fic. God, I have to get back to that and figure out how to write myself out of my block...
But never you mind that. Why not instead, let's just say that the thought of Sam and Santana cuddling and commiserating when Rachel's away makes me all happy, too.
See, because it's really about how the ship/characters makes me feel, that makes me adore it. Could it be Santana and Sam competing for Rachel? Definitely. Could it be Santana and Sam working together to woo Rachel? That's fun too. Could it be Rachel being selfish and cheating on both Sam and Santana with the other? Yes, that could be it, too. And maybe it's not even Rachel as the middle or "focus" of the ship, even if them being all happy together is how it could be, too. Maybe it's Santana who's the focus! Maybe it's Sam! Maybe it's just an appreciation for all three!
Well now, anon, thank you. It's been awhile for me to feel so free and 'shippy', so thank you. It's nice to remember reasons why I love Samchelpez! :D
...But seriously, I do have to get back to my fic...
