Second active fermentation?

Hey guys, I am brewing a summer ale kit by Brewer's Best. Added 1 oz of Citra hops and At the end of the boil I added Orange blossom pure clove honey (12 oz), then I also added 32 oz of blood orange juice. I had a pretty active fermentation for a couple of days. The krausen had dropped shortly after the first round of fermentation and I moved my beer to the secondary at day 14. I added my dry hop to the beer once it was in the secondary fermenter, which was last week (It's been roughly 9 days). A few days ago I added grapefruit peel/zest/a little bit of flesh (which was soaking in vodka) to the secondary. Now it looks to me like there is another round of fermentation. This is my first time adding any fruit at the end of the process and was wondering if this is normal. It looks to me like there is a thinner krausen forming and the airlock is bubbling. I wanted to bottle, but I didn't really want to touch it when it seems like there is some activity going on. Any input would be appreciated. Thank you all!

 

Forgot to mention this is a 5 gallon batch. Airlock is bubbling, but you can't tell in the pic obviously. It looks like the top layer is starting to fall to the bottom, temp. is 64 degrees.

What'd you do? Same thing just happened to me:

 

Fruit has sugar. Yeast eat sugar and create alcohol. So yes you are getting more fermentation.
