You now have another Quirk alongside the one you initially received. This is still limited to any quirk that is not One for All or All for One. The synergies between the two quirks will not be entirely unfounded, do not expect synergies from two quirks that are diametrically opposed. That does not mean it is impossible to develop combinations between your first and second quirk. Two quirks that share some common ground will be able to work together effectively.
