The 22 year old, who signed a new contract with Gloucester earlier this year, told the club website that he didn't spend long with Exeter but it had been time well spent.
"I spent a little bit of time with them during my last year at school and played a couple of times for their United side. So, there will be a few family there but not too many."
"It was good experience playing mens rugby at that age but it was only a few games, I wasn't there that long."
The Chiefs are now well into their second season in the Aviva Premiership and are again acquitting themselves well. Defeat at Sandy Park last season means that Lewis and the rest of his Gloucester team mates are well aware of what to expect on Saturday.
"At home they're especially tough. Their crowd are very passionate and fairly similar to the crowd at Kingsholm so it will be a tough place to go and play."
"They're a very physical side so we're going to have to front up to that and try and impose our game on them."
And the former England U20 international knows that it's important to reduce the error count if Gloucester are to get a result.
"Hopefully we can play as well as we did last Saturday but with fewer mistakes. If we do that, it could be a good game."
"We've let three games slip away from us this season which is disappointing. But I guess the good side of it is that we're not really getting beaten or being outplayed, we're just making frustrating mistakes and that's what has cost us."
"Had we closed out those games, we'd be a lot further up the table. We're not that far off but we do need to brush up on the little things."
