{erik} is helping! {erik.They} and {finn} use different pronouns.
So {finn} can write {erik.theirs} next to {finn.theirs} and it should come out different.
This is easier than just testing by {finn.themselves}.
{ada} asked {finn} for all caps so {ada.they} could shout, but {finn.they} will implement it later."""
