Freer Logion is in one old manuscript, but not in any others. It got in there somehow. It must have been copied in. It may have been copied in to intentionally add to the manuscript, or it may have been copied in accidentally.
If copied in to intentionally add to the manuscript, then it was essentially a marginal note. If copied in accidentally, then it may have been honestly copied in, using a previous marginal note as a model.
