Looking for a class to...
It really depends on his Thief’s spec for weapon, trait, and skill choices. Thief builds can be all over the place, so it’s hard to give a blanket statement. Assuming that he’s playing some kind of cliche D/D glass cannon route, you’d want to play a class that was capable of getting and holding aggro. Yet all of that is pretty subjective.
I’m sure that you know that any class match up would work. Mesmer isn’t the best for holding aggro, but it is a pretty flexible class. If you were both going in and out of stealth and kiting mobs all over the place, then it could be an interesting pair.
So really you need a warrior or a guardian maybe a necro. Not going to do a necro. Maybe a mesmer will do the trick.
What about a engi or even a ranger.
I believe he may play P/P with short bow
P/P is pretty much the lowest consistent dps option that a Thief has available to them. It’s not bad for a single target spike damage option if you really need to fight at range, but people normally use the far superior SB. Combining both together means that he will have a much lower dps output than your average Thief. He’ll be constantly trying to kite mobs around.
You could compliment this with almost anything. A tanky melee oriented Thief could work. Warriors and Guardians are cliche choices, but that doesn’t mean that they aren’t effective. Even the Mesmer, Engineer, or Ranger options would work.
1) Decide what your shared combat style will be. Will one of your tank while the other attacks? Do you make builds to trade aggro back and forth? Perhaps you’ll just kite things all over the place through both of you playing mobile ranged builds. There are a lot of opportunities.
2) As a P/P & SB Thief, he will be horrible in the condition removal department. If you pick a class with some AoE condition removal, then that will help to cover one of his weaknesses. Engineer has some good options with the Elixer Gun weapon and Elixer skill/trait specs. Also both Warrior and Guardian have AoE condition removal. I think that a Spirit spec for a Ranger could also do something like that.

A guardian would be nice to support the thief?
I would suggest guardian too, great support and compliments/buffs the thief’s dps. But mostly go for the one you think looks most enjoyable to play.
