Ethan and Archer argue about whether Ethan should continue working on his "patient." Ethan wants to try again.

Vanessa is trying to sell the MRI to Astrid's parents. Charles calls her out of the room and says to her I thought we decided to pause these tests. He thinks she should chill and rest. Vanessa thinks Charles thinks she doesn't belong here because Maggie is her birth mother. Before Charles can straighten that out, Astrid starts having a seizure. Could be caused by a TBI. Astrid starts to come out of it and Charles wants that MRI after all.
