The 23-year-old admits he enjoyed every second of his spell in the Magners League and Heineken Cup north of the border.
However, he has always kept one eye on life back at Warriors and is now counting down the hours until he pulls the jersey back on and runs out at Sixways once again.
"I really enjoyed my short term loan at Edinburgh Rugby and was pleased to be able to get that opportunity," said the 23-year-old centre.
"It was a fantastic experience in the Magners League and Heineken Cup and I loved my time in Scotland. But it was always going to be short term - I was always coming back to Warriors.
"The club has a promotion race to look forward to and I am look forward to that challenge. I've kept in touch with everyone at Sixways and been back for a few games, I even made it to an A League match up in Newcastle earlier in the season.
"I wanted to keep in contact with the boys, it was important that I stayed involved with everything at Warriors. I wanted to hit the floor running when I got back and not be in the dark and not know the new guys. It makes it easier now on my return.
"The RFU Championship is a big challenge and I can't wait to get started," he added. "I am reregistering and hope to be involved as soon as possible. I don't know when Richard Hill plans to play me of the first time, all I can do it try and push my name into contention."
Grove returns with Warriors playing some impressive rugby to sit at the top of the RFU Championship and he admits he faces a stern test to force his way back into a midfield unit that has gelled in recent months.
He said: "Getting back into the team is going to be a hard task. There are some good players in the centre, but all I can do is concentrate on my game and not worry about other people.
"It is all about healthy competition and we can drive each other forward. Hopefully my involvement can have a positive impact on the squad in the coming weeks.
"My objective now is to try and force my way into the match day squad because I really want to play.
"I feel fresh and fully fit, now I am looking forward to kicking on for Worcester and getting back out in front of the crowd at Sixways."
