I am a little late on the commenting, but i really like these spoiler pictures. I always enjoy seeing interaction between Snow and Regina. I really think this is probably after Snow banishes Regina. I do not think it is when she is the hag because they would just put her in make up. And Snow could go visit Regina because Regina could not harm her at this point.
Though just knowing there will be a one on one conversation between Snow and Regina in this ep is at least enough to know there is one good scene. Hopefully there will be something good on the Storybrooke side.
