"Depended on by" in template

I have a template that sends out informational emails upon new ticket
creation to a team, if unassigned, or an individual if assigned. It
currently just has basic info like:

Requester: {$Ticket->Requesters->EmailsAsString()}
Owner: {$Ticket->OwnerObj->Name}

etc,etc, etc… We would like to also included information on
dependencies, but only if one exists. Anyone currently doing that from
a template, or have any ideas how to tackle it?
