That's only if Arker blood is able to take ALIE 2.0, which we haven't seen yet. But, considering Emerson was immune to radiation because of the bone marrow treatment he received last season, if any of the Arkers can accept ALIE 2.0, then Emerson should theoretically have been fine, too. So, unless Clarke "absorbed" the Nightblood immunity to ALIE 2.0 from being exposed to Lexa's blood, I call BS if she's able to handle ALIE 2.0 without any other explanation except for the Arkers' "genetic engineering."

(And contrary to popular belief, it was NOT Harper's bone marrow.)
