Potential champ Immunity could prove a ‘thorn’ between two ‘Roses’.

The Watchdog expects the flying femme, who is resuming from a 138-day spell, to win at Warragul.

A G2 Laurels finalist, she’s won 11 from 15 (73%) and boasts a sizzling 25.57sec PB over this track/distance.

“A member of a powerful kennel, she should be fully wound up for this assignment and this could be the start of a big preparation,” The Watchdog said.

However, the expert form analyst also says “she runs into a few smart ones” – including kennelmates and litter brothers Jet Lee Rose, who is well drawn, and Stuart Lee Rose, who has clocked a slick 25.75sec at Warragul.

“I can’t wait for this to unfold and to see how well the top elect returns,” he said.
