So me and my DM have been arguing on how Twinned spell works.
When you cast a spell that targets only one creature and doesn't have a range of self, you can spend a number of sorcery points equal to the spell's level to target a second creature in range with the same spell (1 sorcery point if the spell is a cantrip).
I argued that "a second creature" can be a the same target as it is not worded as "another creature"
For this example counter spell with twinned spell.
A wizard casts fireball on me
I use CounterSpell#1 with Twinned Spell
Wizard casts CounterSpell on my CounterSpell#1 I use him as the same
target for my twinned Spell CounterSpell#2
Is this possible?
