And he's looking forward to giving head coach Darren Edwards food for thought.
"It's nice to be back in the Dragons squad and to stay there is going to be a great challenge," he told the South Wales Argus.
"English teams are renowned for having big packs, a driving game and strong scrums so it should be a good contest.
"Northampton have got a fast back line but they are a big team that tries to outmuscle their opponents; they try and turn on the power game."
Ex-Wales hooker Rhys Thomas is currently first choice but there is a scramble to be his back-up.
It is a steep learning curve for Dee, who is a Wales U20 international, but he is aided by former Dragons hooker Steve Jones, who is the region's set-piece coach.
"It's good to have somebody who has recently been on the other side of the fence," he added.
"He understands the training load and what players are going through.
"Jabba can make you think in different ways and help out with little tips. He can communicate as a mentor and Kingsley (Jones, forwards coach) also brings in the technical side of things.
"Then there is Rhys, who is obviously still playing but carries out a similar role. He's always happy to help and it's good to have another person who you can ask questions and who helps you feel more relaxed and comfortable."
