+
+The events and timelines you see are always only what your own time machine knows about!
+
+Of course, time agents don't have to work alone! Here, your sidekick has already prepared a merge for you! You can use the "pull" card to transfer it to your own machine.
+
+Then, add another event on top, and "push" the result, to transfer it back to your sidekick!
