  With discovery of the 125 GeV boson $h^0$, the existence of a second doublet
is very plausible. We show that the "alignment" phenomenon, that $h^0$ is found
to resemble closely the Standard Model Higgs boson, may correspond to Higgs
quartic couplings $\eta_i$ that are ${\cal O}(1)$ in strength. If the exotic
bosons of the second doublet possess extra top Yukawa couplings, which are the
least constrained by data, such a two Higgs doublet model could drive
electroweak baryogenesis, as well as further "protect" the apparent alignment.
The exotic Higgs bosons can be sub-TeV in mass while remaining well hidden so
far, with broad parameter space for search at the Large Hadron Collider.
