So I've realized ANOTHER thing.

Science, Sans, (Classic), Geno, and Error are all the same person.

After x Error shippers, watch out.
Science and Sans shippers, the doors to your left.
Sans x Geno shippers, you're ride is here.
Error x Sans shippers, you may leave.
All ships in between...

*lights a short fuse with the rope tied around the ships*
