I've always wanted for them to hook-up when Derek was with Addison or just not with Meredith. xD Perfect rebound to open his eyes. :)

yeah! I agree! I think it would be great :) LOL. Something about the 2 of them... when Derek was with Addison, I thought It would have been great. Derek would have realized how much he need meredith!

There would be something amazing about them, but not now that mer and der are happy! :)

When Derek was with Addison, I had though about it but I don't think it could really happen.(Meredith wouldn't hurt Derek like this...)Had it happened it would have totally ruined MerDer... And now, even though Mark can be flirty sometimes(but that's Mark,being Mark xD) I think of them mostly like two very good friends, or like brother and sister,(because they really get each other and they've been through similar problems)!

When Derek was with Addison and Meredith and Mark talked in the elevator about the three rules I really thought that they would hook up soon :P

i dnt want it to happen
but if merder got soooo screwed up (HOPE THEY DONT.. EVER)
they mite have been alrite
especially in season 2 :P

The Dirty Mistresses would of been cool XD

no that would be too wierd!

Hell Yes! Love them <33 I've always wanted them together when Derek was with Addison. I mean, I wanted MerDer too but Mark/Mer could be just for a while ;)

I have thought of it, who didn't in the dirty mistress meetings? But I never wanted it to happen. MerDer all the way

Yeah, I mean don't get me wrong. I'm a HUUUUUUUUUUUUUUUUUUGGGGGGGGGGEEEEEEEEEEEE merder fan. But when Derek was with Addison, Mark and Meredith together would have been cool even if just once!

Yeah it would have been cool when Derek was with someone else, otherwise NO. I do read them in fanfiction a lot though :)

it would also ruin Sexie which would really piss me off.
