I loved the Erenville field trip, too. I can understand the reaction being "we need to get back", though. The city was clearly about to become a battle zone and, if nothing else, the twins were there.
What I want to know is, why wasn't sticking our finger to our ear to use our linkpearl to warn them the first thing we did? The writers seemingly just forgot the linkpearls were a thing, even though we made sure the whole group had them back at level 90.And we know we didn't use it of screen cus a character (I think Alphinaud?) says that the ships struck without warning. I'm not saying us sending off a warning would have done much. It would have likely only given our friends a minute or two advantage. But it's a little detail whose omission speaks to the unpolished nature of some of this writing.
