Frozen imperial yeast

[libirm]

Brewed a nice red yesterday, reach into my small fridge in brewing room aka garage and found I unlike the the beer and water in fridge the can of yeast had frozen, warm it up slowly and found some info on web the it would likely be 20/30 % loss of yeast... so I pitched it any way, thinking that I get some us 05 today to add...
But this morning I found the fermenter bubbleing, so should I RE pitch more yeast or let it go?

If I RE pitch, should it be with another can of imperial?
Your thoughts please....

If the yeast sprang into action fast enough for bubbling overnight, I would let it go as is. If you pitch US-05 it will change the flavor and attenuation profiles, and you will end up with something different from your original intent, sans for the case wherein the Imperial yeast was of the same strain as US-05.
