Just read some comments from other fans and I cannot agree with them more about how finally Lena shows her emotions out of her little boxes (possible too many and she can’t stand it anymore when she faces Supergirl...)
I was quite relieved since Lena’s finally screaming and crying in front of Supergirl because that’s an actual step before amending relationship (I hope so)
Lena has her point because Kara is indeed the first person made her to believe that she can trust people again can make friends again and can love and be loved again....
But when she found out Supergirl and Kara is the same person and the feeling of betrayal is coming back again (have to say she’s experienced too many betrayals since everyone around her betrayed her in someways) and now her little boxes can not help her anymore no matter how many simulations she’s done with Hope...
My little poor baby ... just let it out...
I just hope Lena and Kara can talk again and fix this together
