Chain Lightning targets

I did a quick search, but I don't think I saw this question answered:

Do the three targets for Tempest's Chain Lightning need to be different targets?  Can I target a Villain three times with the card, or possibly target Villain-Minion-Villain?

We played it as if the targets must be different, because it seemed a little too powerful, otherwise, but I figured I'd ask for the real ruling.

 

Thanks!

 

Short answer: Yes.

 Long answer: Yeeeeeeeeessssssssss.

Long answer that isn't a tired joke: Chain lightning refers to a second target and a third target. These can't be the same target because then they'd be the first target rather than the second (or third). This wording also applies to Bunker's Grenade Launcher.

A good example of the contrary (targets can be the SAME) can be found in Scherzo of Frost and Flame, which just says "target", not another target, or a second target :)

Similarly Omni-10's Rocket Punch (I think) and Chrono Ranger's Terrible Tech-Strike.
