That is to say, if something happened -- and I've never seen anything like this happen, but I've only been looking for 20 years -- if something happened, they might all come out if they were needed.
Ou seja, se acontecer qualquer coisa - coisa que eu nunca vi acontecer mas só as observo há 20 anos - (Risos) se acontecer qualquer coisa, podem sair, se for preciso.
