I'm hoping to see the lord commanders backstory with John Goodspeed and the titan commander getting out of his cube (a jack in a box... get it...) to help team squad stop Invictus.
I am looking forward to hearing how the group did after it was freed by Ash but personally she has done far worse than the Lord Commander by choosing herself to side with that thing from the prison in Final Space itself the only way she can make it right is with an massive act of sacrifice of her self to make up for her great injustice but the courts would not be so forgiving neither would Arachnitects.
I hope Ash can put things right with Gary and the Team Squad. Maybe those pictures are the start of her realising her mistake she made in the Series 3 finale.
