Backstory: This takes place before the infiltration of the Citadel and after Echo and Fives are ranked up to ARC troopers. Anakin, Ahsoka, Rex, Echo, Fives and the rest of the 501st are on the planet Saleucami hunting Grievous. They engaged several droid tanks and B1 and B2 battle droid and are currently holding their ground.
Ahsoka was blocking blaster bolts from the droids on the left flank next to a blown up AT-TE walker that was on fire. Fives came up from behind some cover and shot down a few droids near the AT-TE. Fives noticed the fuel from the AT-TE was slowly flowing towards the flames next to Ahsoka. Fives stood up and ran towards her.
"Commander! Look out!" Fives yelled. Ahsoka turned around and saw the fuel and the fire getting closer but she had no time to get out of the way. Fives dropped his blaster and grabbed her covering her body with his. The fuel reached the fire and the fire grew bigger then hitting the fuel barrels still in the AT-TE causing a huge explosion. Fives and Ahsoka flew forward away from the AT-TE and hit the ground hard. Fives' armor was breached and there were several burns along his right side and cuts and bruises along his entire back, chest and some cuts on his face. Ahsoka stood up feeling pain in her ribs and grabbed Fives' arm hardly lifting him and carrying him behind cover. Kix ran over and helped her move him behind cover quicker while Echo and two other clones covered them. Kix took off his helmet.
"Fives! Can you hear me? Fives!"
Fives looked at Kix his eyes began to blur and everything began to darken. Everything went black, Fives had passed out from the pain. He later awoke on a cruiser in the med bay. He looked down at his cuts and burns on his side and chest and then at a mirror to see the cuts on his face and bruised eye. Ahsoka walked into the med bay with a bandage wrapped around her ribs and a few smaller bandages on her cheek covering the stitches she got.
"Is Echo alright?" Fives asked her frantically.
"Yeah, he's okay, how're you feeling?" She said softly.
"Like I was almost blown up." Fives replied. Ahsoka sat down next to Fives on the edge of the bed and held his hand.
"If it wasn't for you, I'd be dead. Thank you."
"Just doing what any other trooper would do."
"Maybe, but that doesn't mean I can't say thanks." Ahsoka leaned down and kissed him on the cheek. He bushed pink. "Get better, we need you out there."
