āWhy didnāt Dick and Cassie Sandsmark believe Tim about Bruce being alive?ā
He didnāt actually give them any evidence for it before running away. Didnāt even try to convince them beyond saying āheās alive, Iāll prove it.ā
Heād spent the past year trying to resurrect his dead family and friends. After 100+ cloning attempts and almost stealing Lazarus pit water, this just looks like Timās typical grieving pattern.
Dick, Tim, and Clark personally examined Bruceās dead body and determined it was his!
Timās inner monologue in Red Robin 1 shows even he knows heās driven by desperate hope and compounded grief: āHeās all I have and he has to be aliveā¦Please, god, donāt let me be crazy.ā
If Tim had turned out to be wrong I honestly believe he still wouldāve gone looking for a way to bring Bruce back. Just like he did with Kon, Bart, Steph, Jack, and Janet.
Red Robin follows so clearly from Timās grief from losing Jack Drake and everyone else. DCU Halloween Special ā09: āOur Fatherās Sinsā made this even more obvious by showing Red Robin Tim reflecting on his grief over Jack while heās searching for Bruce.
Of course his friends and family think heās grieving! He is! He just also happens to be right. Nobody is completely unjustified here.
