They'll go back into veg unless it's an autoflower strain. Best to acclimate them, and don't set the pots on hot concrete or asphalt, and try not to let the sun hit the pots directly, or it may fry the roots. Somewhat shaded for the afternoon sun would likely be ok, but someone that grows outdoors would be a better source for this info.

One male can pollinate every female in the neighborhood, so watch carefully for when he starts dropping his pollen. One breeze in the wrong direction, and you'll learn a lot about cleaning seeds out of your homegrown.

If mixing strains, there's no going back. It's mixed forever. If your unknown indica has negative traits, you will see them expressed in the new seeds. (hermapohrodism, genetic mutations...) Likely it will turn-out ok...but I'd want to continue my known variety's genetics before mixing-in an unknown. :thumbsup:
