×In order for the construct to get back from (1), I must explode a fegundo at (2). Unfortunately, this will melt (3) unless the construct used (3) to get to (1).
The construct will not naturally cross (3), so I would need to change its course using the fegundo. Unfortunately, the fegundo needs to explode at (4) on the same turn that the construct is at (5), so it is unable to intercept the construct in time. I cannot find any other way to interact with the construct. I also cannot melt any other part of the path, as there are no obstacles on the path besides the construct (and the force arrows). I also cannot unbrain myself without cutting off my exit.
