What is this plant, please?

On the topic of tomato plants - a couple of weeks ago two tiny rogue tomato plants sprouted (indoors).
Is there any point in nurturing them out of season or should I simply dispose of them?

Nightshade and tomato belong to the same plant family.
And potato.

Thanks grannyknot!

Seeds spread by birds they are edible when ripe, all nightshades are poisonous so wear gloves if you handle them.
