We study the two photon decay channel of the Standard Model-like component ofthe CP-even Higgs bosons present in the type II Seesaw Model. The correspondingcross-section is found to be significantly enhanced in parts of the parameterspace, due to the (doubly-)charged Higgs bosons' $(H^{\pm \pm})H^\pm$ virtualcontributions, while all the other Higgs decay channels remain StandardModel(SM)-like. In other parts of the parameter space $H^{\pm \pm}$ (and$H^{\pm}$) interfere destructively, reducing the two photon branching ratiotremendously below the SM prediction. Such properties allow to account for anyexcess such as the one reported by ATLAS/CMS at $\approx 125$ GeV if confirmedby future data; if not, for the fact that a SM-like Higgs exclusion in thediphoton channel around 114-115 GeV as reported by ATLAS, does not contradict aSM-like Higgs at LEP(!), and at any rate, for the fact that ATLAS/CMS exclusionlimits put stringent lower bounds on the $H^{\pm \pm}$ mass, particularly inthe parameter space regions where the direct limits from same-sign leptonicdecays of $H^{\pm \pm}$ do not apply.
