What to Do With My Big Rainbow Tomato Plant?

[dpurdy]

I've had plants do strange things before but I've never had one do what this plant is doing. The plant didn't have any damage done to it. I've seen plants that have been topped or pinched off and become bushy, but this plant seems to have a mind of it's own. I have many Big Rainbow plants and wonder if I should plant it with the rest or just chuck it? I normally prune and grow with a single main stem in my garden. I wonder if this plant will produce more with all the extra growth? Has anyone else had a similar experience or grown a plant like this one? The last picture is a comparison between two Big Rainbows that were started together.
