Grant Gustin, best known for his role Sebastian on “Glee,” will play Barry Allen aka The Flash, in the second season of Arrow. Gustin will be appearing in three episodes – eight, nine and twenty; and it shall serve as a backdoor pilot to a possible spinoff Flash series.
“Arrow” star Stephen Amell offered some helpful advice and congratulated Gustin via Twitter on Friday, as did co-star Colton Haynes, another recent addition to the series:
Hey @grantgust… You should probably start stretching your hamstrings like… immediately. Congratulations!! #Flash
