+[description]
+
+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 time machine.
+
+Then, add another event on top (what does Sam have for dinner?), and `push` the result, to transfer it back to your sidekick!
+
+You can only ever manipulate things in your own time machine (the one on the bottom).
+

+[congrats]
+
+In reality, in many cases, a lot of time agents work together to build a really good future together! :)
