This is confusing as you don't understand why it's there. A retweet should instead be an entry with a repost-of. With the top author being the retweeter and the inner author being the original tweeter.

Here is an example feed: https://granary.io/twitter/travishinkle/@self/@app/?format=mf2-json&access_token_key=X&access_token_secret=X

The author of the feed is @travishinkle and he retweeted a user (philipnation). There is a retweet on that feed that looks like this:
{ "type": [ "h-entry" ], "properties": { "url": [ "https://twitter.com/philipnation/status/951568325338976256" ], "content": [ { "html": "Prayer is not a spiritual discipline that is separate from the mission of God. It is a discipline by which the Spirit will lead us to our role in the mission of God.", "value": "Prayer is not a spiritual discipline that is separate from the mission of God.
