This is a short drama based on Matthew 21:23-32 and Matthew 9:20-22, with a reference to Exodus 17:1-7. It would be best to read Exodus and Matthew 21 before the drama, and Matthew 9 directly afterwards. The mother here cannot be the woman from Matthew 9, since this drama is set after Matthew 21 (and in the same place) - but her story allows us to imagine that other people may have had similar encounters with Jesus.
Authority and healing are both charged topics, and need handling carefully. It's worth considering where this drama sits in the worship service, and how to set up a space which enables people to engage with the questions raised.
Staging wise, this can be done as a "radio play" with all characters stationary, with just a tea towel and mug from the kitchen as props. Fuller suggestions are in the script if you have the time and space for them.
