In Episode 3 of Season 2, when Allen is attacked by the Viltrumites, he shows no efforts to fight back against them, rather just retorts to making snarky comments which makes him end up in a critical situation. Anything I’ve missed?

P.s. I haven’t read the comics and would prefer not getting spoilers if the reason requires it. Just tell me, it requires spoilers to explain and I’ll wait for the explanation in further episodes.

Thanks.
