It wouldn't survive the experience.
Don't worry about it being in with the vine... It will flower in a day or two... and then... every day for maybe a week... and then... a month to produce viable seed... and will die.
Collect the seed when the pod forms holes on the top.... that's how you can tell that they're ripe.
