Cassidy is following Cassian through the melee when someone knocks into Cassidy from behind and makes him stumble.

The bottle almost slips from his jacket, but he manages to keep a hold on it. However, making a man nearly spill some valuable liquor is a grievous offense.

Cassidy whirls around and finds himself staring into a drunken, snarling, duck-faced Gungan.

"Jaysus, you're an ugly muppet."

He grabs one of its ears and flings him face first into the nearest wall, breaking his snout and knocking him out.

That was for Episode I.

Cassidy hurries toward the back door where he sees Sinya waving people out. He pauses just long enough to give her a peck on the cheek.

"See ya, luv!" he calls back as he dashes after Cassian.
