Today, twitwi output data of cited tweet at the same level of the tweet.
Let's say you have a tweet with only some text (without any link or images) citing another tweet which has links and images, you will get links and images data with twitwi without knowing that they come from the cited tweet. If you have links in both the tweet and the cited tweet, they will be merged together and you will not be able to discriminate them.
It is cool to have these data, but maybe we should have an option to disable this or we could have other columns like cited_links, cited_images…
