hypothetical...hopefully

Ex-Dub to the Caribbean later in the year, two people on the ticket.
If circumstances should mean that one of the two (not the lead) has to drop out of the trip what, if any, impact does that have on the trip?
In other words can the remaining traveller still travel on the ticket without problem?
Tickets are in the cheapest bucket, non refundable etc.
Thanks,
David
PS Parents, who would have them?
