No. We don’t know if it is Robin. We can’t rush to conclusions. Remember, Sean somehow hinted that his character will be there when the baby will be named.
1) She was not rushing to conclusions, because the key word she said is “probably”. Of course we can’t say we know something 100%. It’s called theorizing. It’s what this forum has done for the past 5 Seasons, and we’re not going to stop.
2) How many times do we have to make it clear that we’re fully allowed to theorize whatever we want? You do not have the right to tell us that we can’t, and I’d appreciate it if you’d stop trying to do so.
3) If you have a counterargument, you can do so in a much more respectful manner. We’re open to constructive debates, so long as it’s civil. Saying “we can’t rush to conclusions” is not the right way to go about doing so.
